Thousands of fans lined the streets around Emirates Stadium in London to celebrate the team’s title triumph.
The air thick with red smoke, fans climbed trees, rooftops and traffic lights in the hope of seeing their heroes as the team bus went by.
The London Fire Brigade (LFB) said they had rescued “approximately 75 people” from incidents at height during the event and requested fans to refrain from climbing onto rooftops as the celebrations continued.
LFB also said they responded to a fire incident at a hotel, believed to have been caused by a stray flare.
Assistant Commissioner of LFB, Pat Goulbourne, said: “Fortunately, the fire caused only a small amount of damage to the exterior of the building.
“Pyrotechnics are also believed to have triggered the fire alarms at several other locations in the area.
“As supporters headed home, we urged them to avoid using pyrotechnics, particularly at stations, and to keep them away from buildings and other flammable materials.”
Goulbourne also said the celebrations had been a “fantastic sight” and said so many of the fans were “celebrating their club’s achievement safely”.
The Metropolitan Police said that 16 arrests had been made in the area around the Arsenal parade as of 9pm (2000 GMT) on Sunday.
The force said on the social media platform X that arrests have been made on charges including drunk and disorderly behaviour, drug offences, sexual assault and assaulting emergency workers.
Officers were called to the scene of a stabbing on Hornsey Road just after 8.30 pm and responded with paramedics and the air ambulance.
A man has been taken to hospital, where his condition will be assessed, the force said.
The Metropolitan Police were set to have more than 500 officers staffing the parade.
As the afternoon turned to evening, the streets of north London remained full of Arsenal fans.
The roads were littered with cans, bottles, collapsed e-bikes and general debris from the celebration.
The crowds continued to chant and sing joyously as they made their way back towards the underground Tube stations.
