Three children and two teenagers have been arrested over the murder of an 80-year-old man.
The victim, who was walking his dog in a park in Braunstone Town, Leicestershire, was seriously assaulted on Sunday and died in hospital last night.
A boy and a girl, both 14, and one boy and two girls, all aged 12, have been arrested on suspicion of murder.
The attack happened near the entrance to Franklin Park in Bramble Way at about 6.30pm.
The victim is believed to have been wearing a black jumper and grey jogging bottoms.
Police said the people who attacked him left before emergency services arrived.
Detective Inspector Emma Matts said: “We still need people who were in the area to come forward if they have seen anything or have any information which could assist.
“Were you in the area of Franklin Park or Bramble Way around 6.30pm on Sunday night?
“Did you see the attack itself? From the description given did you see the victim before the incident or possibly a group of young people leaving the area after?”
Police said officers are still at the scene and that “reassurance patrols” are taking place in the area.
Braunstone Town is located about 2.5 miles (4km) southwest of Leicester city centre.
Due to prior contact with the victim, Leicestershire Police will also refer itself to the Independent Office of Police Conduct (IOPC).
