Lincolnshire Police are investigating after the Mansfield Town team bus was attacked following their victory over Lincoln City at the weekend.
The Imps lost for the first time at home in 364 days after their neighbours from Nottinghamshire won a tight game 1-0, thanks to a second half goal from Danny Rose.
A Mansfield fan was charged with throwing a missile at the game and will appear in court next month.
However, it has now emerged that crowd trouble was not confined to the away supporters.
In a statement, Lincolnshire Police said that Mansfield Town have informed them that their bus was attacked at St Catherine’s at around 4.15pm on Saturday, September 16.
The force is looking for six or seven youths, aged between 16 and 18.
Superintendent Lee Pache said: “This attack was carried out by a group of five or six youths and objects, believed to be bottles, were thrown at the bus and have caused approximately £1,000 of damage, as a body panel needs to be replaced.
“The group were also extremely abusive to the players and staff on the bus.
“The boys are believed to be aged between 16 and 18 and one was wearing blue shorts with a grey hoodie. He is approximately 5ft 11 and of a skinny build.
“Both we and the club are scanning CCTV to find these individuals but I would encourage them to come forward before we find them by speaking with Lincolnshire Police. If this was you, please accept responsibility and call 101.
“We also encourage fans and residents to report information to us.
“Although this has been caused by a minority it reflects badly on the city and fans, the vast majority of who behave impeccably every game.
“Again please call Lincolnshire Police if you can help or report anonymously to Crimestoppers on 0800 555 111.”
Earlier this week Mansfield Town manager Steve Evans told the Mansfield and Ashfield Chad: “It wasn’t very nice, but we will leave that to other people.
“I think the police and football authorities have enough issues, especially on derby days but it wasn’t very nice.”
