Paolo Di Canio has been accused of carrying out a midnight raid on his old Swindon Town office and tearing down pictures of his time as manager, reports The Guardian.
The Italian reportedly entered the County Ground stadium in the early hours of Thursday morning, using keys he had kept after resigning on Monday.
Di Canio and three members of his coaching staff were allegedly captured on CCTV entering the office and removing the mementos of his 21 months in charge.
The League One side are believed to have changed the codes on the stadium entrance and replaced the locks to the office to prevent any repeat.
They have declined to comment, as has Di Canio, but it is understood they have not passed the matter on to police and will not take further action.
