Police have released images of several men they would like to speak to following incidents on the day of the Arsenal Premier League victory parade.
Detectives are appealing for any information in relation to the four incidents on May 31 in Islington.
Police wish to speak with one man after a report of racially aggravated assault against a woman on Upper Street at around 2.30pm.
In a second incident, police are looking to speak with a man in connection with a person damaging a car at 3.15pm on Caledonian Road.
Detectives also wish to speak with a third man after a woman was assaulted on Highbury Crescent at around 4.30pm
In the fourth incident, two men sustained serious injuries following an assault at 10.31pm at the King’s Head on Upper Street.
Police are looking to speak with six men in connection with the fourth incident.
None of the four incidents are connected.
On the day of the parade, officers made 29 arrests, including for stabbings and assaults.
Twelve people have already been charged for offences including attempted murder, grievous bodily harm, assault on an emergency worker and sexual assault.
Detective Chief Inspector Phil Coster, from the Metropolitan Police Service, said: “These incidents occurred on a day when fans should have been able to enjoy celebrations safely with family and friends. Instead, we saw a small number of individuals engage in behaviour that put others at risk.
“More than 500 officers were deployed across the event alongside specialist search and drone teams. Their presence helped ensure the vast majority of supporters were able to enjoy the celebrations safely.
“While the event was largely safe and brought thousands of fans together to celebrate, we did see instances of disorder, anti-social behaviour and some violent incidents.
"We are continuing to carry out enquiries to help progress our investigation and identify those responsible. If you recognise any of the men pictured, or have any information that could assist our investigation, please get in touch with us."
Anyone with information should call 101 with reference 7135/25Jul. Alternatively contact independent charity Crimestoppers anonymously on 0800 555 111.
