Atul Shah's family pleads for answers after his murder
Relatives of a man found murdered in his home just over a week ago say they are "desperately seeking answers".
Atul Shah, 47, was found dead in Crescent Road, Luton, on 6 January.
His family said: "We are completely devastated and totally heartbroken that this has happened to Atul.
"We are desperately seeking answers. We urge anyone with any information to come forward ASAP." Mr Shah was described as a "lovely man with a heart of gold and a zest for life."
Police officers from the Bedfordshire, Cambridgeshire, and Hertfordshire Major Crime Unit have launched a murder investigation but have not released details of how Mr Shah died.
Senior investigating officer Det Insp Justine Jenkins said she was "certain someone somewhere has the information we need".
"We're also still keen to hear from any of Mr Shah's friends who have not yet been spoken to by police."
She asked anyone who was in the area around the time of the body's discovery to try to remember whether they saw "anything out of the ordinary".
On Tuesday, a further two people were arrested on suspicion of Mr Shah's murder, bringing the total number of arrests to six. All have been released on bail.
