Police are investigating six stabbings after Arsenal's Premier League title-winning parade in London on Sunday.
Some 24 people were arrested at the event, the Metropolitan Police said, with the force thanking "the vast majority of people" who celebrated "safely and responsibly".
Among those arrested were 10 people on suspicion of assault on police. One officer suffered a slash wound to the hand and another was hit on the head, both from objects thrown at them, the Met said.
Three people were detained on suspicion of sexual assault, while one person was arrested on suspicion of grievous bodily harm after an assault causing a head injury.
Three people were arrested over alleged drugs offences, one of whom was also held on suspicion of having a lock knife.
Police said officers dealt with "six stabbings on the parade footprint" later in the evening after most of the crowds had dispersed.
One man in his 20s was taken to hospital in a life-threatening condition but is now stable.
Damage was also caused to four police vans in Islington, north London.
Commander Stuart Bell, who led the Met's public order operation this weekend, said most of those attending behaved "safely and responsibly".
He pointed to "pockets of anti-social behaviour and incidents where officers needed to intervene, including assaults on their colleagues.
