Some 93 people were treated for burns after flares were lit during PSV Eindhoven’s title celebrations on Tuesday, even though the city had imposed a strict fireworks ban in the wake of injuries at last year’s parade.

Most of the injuries were mild and no one needed hospital treatment, the local authority said. The casualties were treated at first-aid posts set up around the Stadhuisplein and the Markt, where tens of thousands of fans had gathered to watch the squad appear on the city hall balcony.

Red flares were set off in the crowd as the players arrived, filling the square with thick smoke – a familiar sight at PSV celebrations but one the council had hoped to prevent this year.

Eindhoven had announced ahead of the parade that it would strictly enforce a ban on fireworks and flares following problems at last year’s title party, when around 60 people reportedly turned up at first-aid stations with burns and 14 police officers were injured by fans throwing rocks, glasses and fireworks.

Police said 17 people were arrested during Tuesday’s festivities, several of them for fireworks-related offences. Officers seized tens of kilos of fireworks in and around the two main squares, which the council said suggested the ban had at least partly worked.

The local authority described the celebrations as having gone well “on the whole”, with no major incidents. Officials said they would sit down with PSV and the event organisers in the coming days to evaluate how the parade was run and whether tougher measures are needed next time.

The club, coached by Peter Bosz, sealed its 27th Eredivisie title on Sunday after nearest rivals Feyenoord could only draw at Volendam. It is PSV’s third championship in a row and the 12th this century, making the Brabant side the most successful club in the Dutch top flight since 2000.
