The son of Helsingborg coach, Henrik Larsson, was attacked on the pitch by fans after the club’s relegation was confirmed on Sunday.
Jordan Larsson was confronted by a group of Helsingborg supporters at the end of the 2-1 defeat to Halmstad and had his shirt removed.
The 19-year-old forward had scored to put his side ahead with eight minutes left against Halmstad, but two late goals from Marcus Mathisen condemned Helsingborg to relegation from the Allsvenskan after a 3-2 aggregate play-off defeat.
Fans came on to the pitch and tried to confront Celtic, Barcelona and Manchester United striker Larsson, who has been in charge at his home town club – with whom he had two spells as a player – since 2015.
A statement from director Mats-Ola Schulze on the club’s website read: “The events that took place after today’s game were unacceptable. Helsingborgs IF strongly reject this because it is contrary to our values . We will return with a statement about this when we have created a comprehensive picture.”
Manager Larsson told the Swedish press: “I understand their frustration. That’s why I went over there too. It was not the smartest thing for me to do.
“I did not see that they were attacking Jordan, but if I had I would have gone in there.
“I live and work here in town. I will look over my shoulder a little more and make sure not to walk alone in town.
“If they (hooligans) come, they come. We have many dogs at home.”
