Manchester and Kent Police are investigating allegations that current and former executives at fashion retailer Boohoo were subject to harassment and surveillance.
Greater Manchester Police said they were investigating allegations “involving serious distress” but no arrests have been made.
The Times newspaper reported that alleged stalking offenses were committed against Boohoo co-founder and executive chairman Mahmud Kamani, chief executive Dan Finley and his former boss John Lyttle.
A Boohoo spokesperson said: “It would be inappropriate to comment while a police investigation is ongoing.”
The Information Commissioner's Office (IOC) said Boohoo informed them of a possible surveillance incident outside the retailer's Manchester headquarters.
“We can confirm that Boohoo Group has raised concerns with us about the discovery of surveillance equipment outside its head office,” a spokesperson for the information watchdog said.
Greater Manchester Police said: “An investigation is ongoing into harassment involving serious alarm/distress, and no arrests have been made at this stage. »
Kent Police said they were “investigating stalking offences, particularly in the Sevenoaks area”.
“Investigations are ongoing and no arrests have been made,” he added.
Mr Lyttle, who left his role as chief executive of Boohoo in October after five years at the helm, was approached by the BBC for comment.
Mr Lyttle's departure follows Boohoo's announcement that it was considering a major restructuring and possible break-up of the business, believing the business remained “fundamentally undervalued”.
Separately, Frasers Group, which is Boohoo's largest shareholder, criticized the company's management, recent results and business review. In an open letter to other shareholders, Frasers also said it wanted to install Mike Ashley on the Boohoo board.
In response, Boohoo said: “Frasers appears intent on disrupting the analysis of Boohoo's business and acting solely in its own commercial interest. »
Mr Ashley is the founder of Sports Direct and has built a retail empire including House of Fraser, Flannels and Evans Cycles, housed under parent company Frasers Group.
Shareholders will be able to vote on Frasers Group's proposals for Boohoo at an extraordinary general meeting in Manchester on Friday 20 December.
