THREE men arrested in connection with the death of a teenager in Reading have been released.

The un-named schoolgirl, who was aged 16, was found stabbed and possibly shot in a Reading park.

An 18-year-old teenager was also injured in the attack and was found stumbling around with gunshot and stab wounds. She is currently stable.

The two incidents are believed to be linked.

Det Supt Mark Warwick, senior investigating officer, said: "This is a rare and terrible crime and we need people's help to find out who is responsible."
