Hertfordshire man found dead in burning bungalow
A man has been found dead in a burning bungalow in Hertfordshire.
The victim, believed to be in his 60s, died in the blaze at his home in Westerdale, on the Highfield estate in Hemel Hempstead, in the early hours of Saturday.
A 30-year-old man has been arrested on suspicion of murder.
Neighbours were evacuated from their homes after firefighters discovered a hand grenade in the property. It was found to be inert.
The device is not being linked to the investigation, said a police spokeswoman.
Det Ch Insp Mark Ross said: "Although this incident occurred during the night, the property is in a residential area and there may have been people who may have seen or heard suspicious activity in the area.
"I would appeal to anyone who believes they can assist the investigation, to contact us as soon as possible."
