Police in Manchester and Kent are investigating claims that current and former executives at the fashion retailer Boohoo have been the victims of stalking and surveillance.
Greater Manchester Police said it is looking into allegations "involving serious distress" but no arrests have been made.
The Times newspaper reported that alleged stalking offences were committed against Boohoo's co-founder and executive chair Mahmud Kamani, chief executive Dan Finley and its former boss John Lyttle.
A spokesperson for Boohoo said: "It would be inappropriate to comment whilst a police investigation is ongoing."
