A Worcester man, who was killed after an arson attack on his home, was a convicted paedophile, according to West Mercia Police.
Andrew Heath, aged 52, was found dead at his flat in Warndon last December.
Police confirmed he was convicted for gross indecency and indecent assault against teenage boys five times during the 1980s and 1990s. These assaults happened in Leicester and Birmingham- before Mr Heath moved to Worcester.
Detective Chief Inspector Paul Williamson, who is leading the operation, said:
""I have taken the decision to make public details of previous offences committed by Andrew Heath because it may have some bearing on our inquiries.
"Since his death a lot of rumours have been circulating around the local community in Warndon about Mr Heath, some of them quite fanciful, and we believe these may have hampered our investigation. We wish to set the record straight and use this as another opportunity to appeal to the public for any information".
West Mercia Police say they have no records of any offences or complaints against him since he moved to Worcester.
DCI Williamson said:
A total of 10 people have been arrested over his death. To date, nobody has been charged.
Police increased the reward for information leading to finding Mr Heath's killer from £10,000 to £20,000.
