Police have been contacted with new information about David Sullivan following a BBC Panorama and Times investigation into the West Ham co-owner.

Essex Police said there had been "some contact and enquiries into those are now under way" after the joint investigation was published on Monday. The investigation revealed that multiple women have accused Sullivan of sexually exploitative and predatory behaviour dating back from the 1980s. Sullivan has categorically denied the allegations.

Culture Secretary Lisa Nandy has held urgent "fact-finding" meetings with the Football Association (FA) and West Ham after the BBC revealed Sullivan was banned from contacting the women's and youth teams over safeguarding concerns. Sullivan has been under the restrictions for three years after a historic allegation about his conduct was raised with the FA in 2023. The restrictions had not been public and he continued to attend men's first team matches.

In a statement issued on Wednesday, Sullivan said he had never met any academy or women's team players "1-2-1" during his 16 years at West Ham. He said the complaint "had nothing to do about my time in football and it never happened". "I saw it as a meaningless restriction, as it didn't impact on my work in any way, therefore I accepted it for a quiet life," he said. Sullivan said it was inaccurate to describe this agreement as a "disciplinary 'ban'".

In response, Nandy called for a "full and urgent explanation" of how the "incredibly serious allegations" about Sullivan had been handled. She had meetings with West Ham and the FA on Wednesday to seek answers on its response to the safeguarding concerns.

West Ham is understood to have made clear it was confident in its "robust safeguarding measures". Meanwhile, it has emerged that Boyle Sports, one of West Ham's main sponsors, had not been made aware of the restrictions placed on Sullivan. In a statement, Boyle Sports said it was "extremely concerned at the serious nature of the allegations levelled against David Sullivan". "It is our understanding that the Independent Football Regulator is reviewing this matter urgently and we wholeheartedly support their efforts in doing so," the statement added.

The BBC and Times investigation also revealed that eight women, including one who was part of the investigation, have gone to the police with disclosures about Sullivan's conduct. None of those cases have resulted in charges.

Sullivan, 77, held the joint chairman position at West Ham for 16 years, and was the club's largest single shareholder following the death of his business partner, David Gold, in January 2023. He resigned as joint chair on Saturday, saying he wanted to focus on fighting what he called "factually incorrect and entirely false, decades-old allegations concerning my personal life".

In his resignation statement, Sullivan said that "after a lifetime spent building businesses in the adult industry in which I have met thousands of women, it is sadly inevitable that a small number of improper conduct claims are being made against me". West Ham and the FA have previously said they have clear and robust safeguarding measures in place, and were unable to comment on individual cases.
