Two more people have been arrested in connection with the death of a man in Worcester.
Andrew Heath, who was originally from Leicester, was found dead at his home in Warndon in December after a suspected arson attack.
Police believe his death could be linked to his convictions for sexual offences.
It follows four recent arrests. One person is being held on suspicion of murder and three on suspicion of perverting the course of justice.
