 CANARSIE, Brooklyn — A robbery victim, who decided to take the law into his own hands by mowing down an armed teen thief, severing his right arm, is now in handcuffs himself, police said. 
 
 Police arrested the robbery victim, Philip Pierre, 39, of East Flatbush, Brooklyn, and charged him with attempted murder. The alleged teen thief, Zachary Sam, 17, also of Canarsie, Brooklyn, was charged with robbery and criminal possession of a weapon in the Craigslist robbery gone wrong. Both were charged on Friday. 
 
 Police sources say the teenager connected with Pierre on Craigslist on Friday. Pierre was selling a pair of Air Jordan sneakers. 
 
 They met about 1 p.m. near Avenue M and East 84th Street in Canarsie, where Sam got into Pierre's Honda Pilot SUV and pulled out a gun, a police source said. The teen allegedly stole the Jordan Retro 8 sneakers and walked away. 
 
 Sam managed to make it only about 100 yards with the shoes when the driver made a U-turn, stepped on the gas and struck Sam. The teenager was pinned against the fence and his right arm was severed "completely," a police source told PIX11. 
 
 "He technically did disarm him," a police source said. 
 
 Missing his arm, Sam tried to jump on an MTA bus, where he demanded a MetroCard. Just then, Pierre yanked the teenager off the bus and told the driver he'd robbed him. Then Sam escaped his clutches again and ran home, where he collapsed outside, a police source said. 
 
 An ambulance took Sam— and his severed arm — to a Brookdale Hospital. The teen was listed as critical but stable condition. Doctors surgically reattached his arm Friday night, but are not yet sure if the operation was successful, a police source said.

 Pierre was arraigned Saturday on attempted murder charges. He is being held on $100,000 bond. 
 
 Pierre's relatives said his actions were done in self-defense. 
 
 "He was just there to help support his family," Pierre's cousin said. "What would you do if someone pulled a gun on you?"

 An alleged robber lost an arm when a man from whom he stole a pair of Air Jordan sneakers chased after him in an SUV and hit him, pinning him against a fence in Brooklyn, police say and surveillance video shows. 
 
 The alleged robber, 17-year-old Zachary Sam, was armed when he met with 39-year-old Phillipp Pierre, who thought he was selling Air Jordans to a buyer he met on Craigslist early Friday afternoon, police said. 
 
 But when Sam entered Pierre's car at East 84th Street and Avenue M in Canarsie, he pulled a gun on him and demanded the sneakers, police said. 
 
 A relative of Pierre, who asked not to be identified, told NBC 4 New York: "He put the gun to his head and told him he would shoot him, that he will not make it home to his family." 
 
 Surveillance video shows the teen getting out of Pierre's SUV with a bag containing the sneakers and calmy walking away, out of the video shot. The SUV also pulls away. 
 
 The teen then walks back into the shot, and the SUV suddenly zooms in from behind, mowing him down. 
 
 Pierre gets out the car, video shows, and he and Sam appear to scuffle as a crowd starts to gather. Sam then manages to flee, despite losing an arm in the crash, according to police. He collapsed in front of his home down the block. 
 
 Sam was taken to Brookdale Hospital, where he was listed in serious but stable condition. He was charged with criminal possession of a firearm and second-degree robbery. 
 
 The SUV driver and robbery victim, 39-year-old Phillipp Pierre, was also arrested. He's being charged with second-degree attempted murder. 
 
 It's not clear if either man has retained an attorney. 
 
 Pierre's relative said he did not hit the teen intentionally. 
 
 "The kid pulled out the gun to shoot him while he was in the car, and that's when he tried to protect himself," the relative said. "That's why he accelerated and that's when it happened."

 "He's a very good man, he was making money for his family," the relative said. 
 
 It's not clear what happened to the teen's arm lopped off in the crash.
– An eye for an eye... and an arm for a shoe? The NYPD says a 17-year-old in Brooklyn who stole a pair of Air Jordans at gunpoint lost an arm when the victim ran over the teenager and pinned him against a fence, PIX11 reports. The teen, identified as Zachary Sam, allegedly used Craigslist to arrange to meet 39-year-old Philip Pierre to buy the $190 sneakers, but instead pulled a gun when he got in Pierre's SUV. "He put the gun to his head and told him he would shoot him, that he will not make it home to his family," a relative tells NBC 4. Sam strolled off with the sneakers, but surveillance video shows he only made it 100 yards before Pierre did a U-turn and ran him down, police say. According to PIX11, Sam tried to get on a bus after his arm was severed but Pierre pulled him off the vehicle in front of horrified passengers. The teen then ran around the corner to his home, where he collapsed. Pierre has been charged with attempted second-degree murder. A cousin tells ABC7 that the hard-working father of three was only trying to detain the teen for police. "I know what the video's showing—if somebody pulls a gun in your head, and you're trying to get the cops to catch him, what would you do?" he says. "You're telling me just let him go?" Sam's arm—and gun—were found at the scene. Doctors at Bellevue Hospital spent hours trying to reattach the limb, though it's not clear whether they succeeded. ABC7 reports that the teen will be going to jail when he gets out of the hospital.
