A woman was thrown to the ground and had a gold chain worth hundreds of pounds pulled from around her neck in a vicious street robbery.
The victim hit her head on a wall during the booze-fuelled attack on Reads Avenue, police said.
Following an altercation, the offender is alleged to have dragged the victim to the ground by her hair before forcibly pulling a gold chain from around her neck and running off
Detectives are today continuing their investigations into the robbery, which took place at around 6pm on Wednesday.
It is believed an argument between members of a group became heated, prompting the attack.
Det Sgt Steve Harry, of Blackpool CID, said it is thought the victim knew her attacker.
A woman who was arrested in connection with the incident has been bailed by police pending further inquiries.
Det Sgt Harry added: “There was a group of six or seven people, all known to each other and under the influence of drink, in the street.
“Following an altercation, the offender is alleged to have dragged the victim to the ground by her hair before forcibly pulling a gold chain from around her neck and running off.”
He said it is possible there were other people in the area at the time who witnessed the robbery.
He said they would have seen a group of men and women arguing in the street.
Detectives are also keen to trace the gold chain that was reported stolen in the robbery.
Det Sgt Harry added: “the victim has a lump on her head as a result of hitting a wall when she was pulled down.
“There is still an outstanding gold chain, worth £300, that we have yet to find.”
A 30-year-old woman from Blackpool was arrested on suspicion of robbery. She has since been bailed until Tuesday.
Another woman who was arrested in connection with the incident has been released without charge.
Anyone with information is asked to call Blackpool CID on 101.
