 A lion has attacked an elderly man in Kenya's capital, Nairobi, after straying from a nearby national park. 
 
 The animal became agitated with people hooting their horns and taking selfies, a wildlife official said. 
 
 The lion has returned to the park and the 63-year-old man is in hospital, Paul Udoto, spokesman for the Kenya Wildlife Service said. 
 
 The city was put on high alert last month after several lions escaped from the park, causing panic. 
 
 A video circulating on social media appears to show the lion wandering along a busy road during morning rush hour. 
 
 Rangers are still on the streets of the city in case there are other lions around that have not been spotted, Mr Udoto added. 
 
 The park is separated by a main road from densely populated neighbourhoods, including Kibera slum, in the south of the city. 
 
 A loss of habitat for lions in the city means they are increasingly coming into conflict with human populations, putting their survival at risk, Kenyan conservationist Ali Kaka told the BBC. 
 
 "If there is no prey or there isn't enough prey in the park the animals may decide to wander out," he added. 
 
 Nairobi National Park is fenced in on the city side but is open elsewhere to allow for the annual wildlife migration. 
 
 In 2012, four cubs had to be placed in an orphanage after a similar incident led to their mother being killed. 
 
 What to do if you spot a lion: 
 
 Do not confront the animal 
 
 Do not make noise 
 
 Do not throw anything at the animal 
 
 Do not run 
 
 Do not panic as the animal may sense this and react

 NAIROBI, Kenya (AP) — A lion left Nairobi National Park, walked alongside a highway full of rush-hour traffic and mauled a 63-year-old pedestrian Friday before being captured, officials said. 
 
 The man had been "clawed in two areas, on the front of the chest and on the back of the shoulder. He sustained lacerations, quite deep cuts in the left shoulder region and has sustained a small fracture in one of the bones in the area," said Victor Ng'ani, the director of Mater Hospital. 
 
 The lion went by The Star printing press. Wellington Lwenya, a plumber there, said it was terrifying to come face-to-face with the lion, the newspaper reported. 
 
 The lion attacked after becoming agitated by motorists honking their horns, said Kenya Wildlife Service spokesman Paul Udoto. 
 
 A video circulating on social media show the lion walking on a sidewalk amid a cacophony of honking horns. 
 
 Some Nairobi residents are getting concerned by the growing number of such incidents. 
 
 "We are worried for our lives," said Michael Kimani, a Nairobi resident who saw the lion. 
 
 Nairobi National Park, which covered 117 square kilometers (45 square miles) on the outskirts of Nairobi, is home to endangered black rhinos, lions, leopards, cheetahs, giraffes and diverse birdlife. It is partly surrounded by an electric fence. 
 
 In February, six lions walked out of the park and roamed through the city, scaring residents for a few hours before the big cats returned to the reserve. 
 
 Occasionally lions clash with people on the southern side, which is not fenced. 
 
 In 2012, six lions were killed after the pride of eight lions attacked and killed eight goats of Maasai herdsmen. Only about 2,000 lions are left in Kenya after years of hunting and then poaching. 
 
 The government has announced plans to build a railway that will traverse part of the reserve. Conservationists have opposed the railway line, saying it will further damage wildlife habitat.

 A 63-year-old man was injured during a lion attack on Friday after the animal wandered out of Kenya's Nairobi National Park onto a major highway during the height of morning traffic, the Kenya Wildlife Service (KWS) reported. 
 
 Paul Udoto, a KWS spokesman, said the black-maned lion swiped at the man after it became agitated by horn-honking from passing cars. 
 
 "People were there, hooting their horns, taking selfies and all that, and the lion got agitated," Udoto said. He added that the injured man was taken to hospital and is in stable condition. 
 
 Following the incident, the male lion returned to the park, followed by rangers who encouraged it to move deeper into the reserve. 
 
 "The lion is safely back, but our teams are still on the ground in case there are any others around that have not been spotted," Udoto said. 
 
 Lions 'on the loose' or humans too close? 
 
 A video circulating on social media shows commuters incessantly honking their horns as the large lion runs along Mombasa Road, a traffic-packed four-lane highway in Nairobi. Some looked on at the lion from behind a closed iron-bar gate. 
 
 Animals in Nairobi National Park roam just 10 kilometers (six miles) from downtown Nairobi. Kenya's big cats are increasingly strained as the fast-growing city of over three million expands onto the animals' ancient migration routes and hunting grounds. 
 
 Conservationists argue that lions are neither "escaping" from the parks nor "straying" into human settlements; lions, they say, predate people in the area and people have moved into the lions' home ranges. 
 
 Last month, two lions spent a day wandering through Kibera, a densely packed Nairobi slum, before returning to the park. Although lion sightings are becoming more common in the bustling capital, it is unusual for anyone to be injured during the animals' outings.

– A warning: When a lion is on the loose, it's best to keep your distance and skip the selfies. A 63-year-old man is recovering in a hospital after a lion strayed from a national park in Kenya on Friday. The black-maned lion was spotted prowling beside a four-lane highway in Nairobi during morning rush hour, reports the BBC. A rep for the Kenya Wildlife Service tells Deutsche Welle that it clawed the man—who suffered a broken bone and deep cuts to his shoulder, per the AP—because people were "hooting their horns, taking selfies and all that, and the lion got agitated." The lion was later escorted back to the reserve.
