A local taxi driver may have key evidence in a robbery case, police said.
The appeal to identify the mystery driver comes after a woman in her 20s was mugged near Wilko Superstore on Dickson Road in the town centre at 1am on Wednesday, April 3, 2019.
The woman, who had just withdrawn cash from a nearby ATM, was punched in the chest, and had the money snatched from her pocket.
Police later arrested a 32 year old man and a 25 year old woman on suspicion of robbery and assault, but both were released under investigation.
After the attack, the woman approached a nearby taxi driver, who offered to take her home free of charge.
Officers have not yet managed to trace the taxi driver, despite having contacted several local firms.
They are now appealing for them to come forward, as they "may hold vital information to our investigation".
Anyone with information should email firstname.lastname@example.org or call 101 quoting log number 1105 of 5th April.
A 25 year old woman from Blackpool was arrested on suspicion of robbery and has since been released under investigation pending further enquiries. A 32 year old man from Blackpool was arrested on suspicion of robbery and assault and has been released under investigation pending further enquiries.
