Portsmouth manager Harry Redknapp branded the abuse of Campbell 'filthy'
Police are to investigate racial and homophobic abuse directed at Portsmouth and former England defender Sol Campbell at Fratton Park.
The Portsmouth captain was subjected to taunts during his team's 2-0 Premier League home win over Tottenham on 28 September.
The 34-year-old is unpopular with Spurs fans after moving on a free transfer to north London rivals Arsenal in 2001.
Police initially said the scale of the taunts meant no arrests could be made.
Hampshire Constabulary said it received a complaint about the abuse on Tuesday night.
"The complaint will be fully investigated but it is at an early stage," a spokeswoman said.
The force originally said it would refer the matter to the Football Association (FA) because "it was not feasible to make arrests in that kind of huge crowd".
The FA had said it would "take action where necessary".
Portsmouth's manager, Harry Redknapp, branded the verbal attacks as "filthy".
"Nobody likes being called filthy names and hearing other filthy abuse," he said.
"It's not right. What has that got to do with coming to a game?"
Campbell left Spurs on a free transfer in June 2001 to join rivals Arsenal.
He then joined Portsmouth from Arsenal in August 2006 on another free transfer.
