Banned fans' warning over Wembley FA Cup semi-finals
More then 190 letters have been sent to people on football banning orders warning them not to attend this weekend's FA Cup semi-finals.
Manchester United are due to play Manchester City at Wembley on Saturday. Bolton Wanderers will take on Stoke City on Sunday.
Football Intelligence Officers will be on the look out for the 196 people on orders, ticket touts and troublemakers.
Police said those on orders face arrest if they attend the games.
The banning orders are issued for offences ranging from drunken behaviour, through to assault and violent disorder.
The Metropolitan Police has advised fans travelling to Wembley to only travel by public transport, not to go to without tickets, and to allow plenty of time to get to the ground and inside.
Greater Manchester Police (GMP) urged supporters staying in Manchester on Saturday to stay safe by avoiding drinking heavily.
Ch Supt John O'Hare, said: "We know that people are going to want to go out and have a drink or two this weekend and that emotions can run high, but what I'd say is make sure you take care of yourself when out and about."
GMP has reported increases in domestic abuse incidents during major sporting events and is offering extra support to victims.
Det Supt Phil Owen said: "We are sending a clear message that there is no excuse at any time for domestic abuse and I would also like to reassure victims that we have specialist domestic abuse investigators on hand to provide support from the initial report throughout the investigation and during court proceedings.
"It is also important to stress that we can also act on information given to us from friends or family members of victims and I would encourage them to seek help and advice immediately before the abuse escalates.
"Offenders also need to be clear that a football match cannot be used as justification for any abusive behaviour."
