An 18-year-old man has been arrested on suspicion of murdering Leonne Weeks, 16, who was found dead on a path in Rotherham.
Police are looking for a cyclist after a woman dog walker was stabbed in Bedford following an argument with him.
The 38 year old victim had been walking her dogs near Norse Road on the afternoon of Thursday 19 July 2012, when the animals' leads became tangled with the biker.
Detectives say he then pulled out a small knife a stabbed her in the stomach.
The woman had been walking her dogs next to a cycle path which runs between Thor Drive and the Go Outdoors store at 1pm.
They say the cyclist stabbed the woman in the stomach with a small knife before fleeing towards the housing estate next to Thor Drive.
The victim was able to contact Bedfordshire Police on her mobile phone and officers went straight to the scene with paramedics who have taken the victim to Bedford South Wing Hospital where she was treated for a small puncture wound.
The offender is described as a mixed race male, aged around 18, of slim build and with short or possibly shaved black hair. He was wearing a dark grey hooded top and black jeans and was riding a silver bike.
DS Mark Crone, who is leading the investigation, said: “This was a seemingly unprovoked assault and we are keen to trace the offender as quickly as possible.
"The attack happened close to a busy road and an industrial estate as well as the Go Outdoors store and I’d like to hear from anyone who was in the area at 1pm and may have seen the offender on his bike.”
Officers have been carrying out house-to-house enquiries and they have been looking through CCTV footage that covers the local area and business premises.
Anyone with information about what happened is asked to contact Bedfordshire Police, in confidence, on the non-emergency number 101, or text information to 07786 200011.
