A man has punched the victim causing him to hit the ground, he has then stamped on his head
On Friday, a 79-year-old man from Scotland was attacked by a gang who stole cash from him.
The attack happened on Vance Road at 10.50pm.
The victim was visiting Blackpool just for the night as he made his way to Aintree for the Grand National on Saturday.
He was attacked as he took a late night stroll near his hotel to get some fresh air.
Det Sgt Rick Irving, of Blackpool CID, said the gang were waiting in an alleyway when the elderly man walked past.
One member of the gang knocked the man to the pavement, while the others searched through his pockets as he lay helpless.
Det Sgt Irving said: “While on his walk, a group of four or five people have attacked him as they waited in an alleyway.
“One member of the group hit the man on his left side of his head forcing him to hit the ground.
“While he lay on the ground, they went rummaging through his pockets for money and stole between £40 and £50.”
The elderly man was left “badly shaken” by the attack but still managed to to make his way to the Grand National.
In the second incident a 45-year-old man was attacked and knocked unconscious outside the Cube nightclub in Poulton.
He was punched and fell to the ground before his attacker stamped on his head leaving him with serious cuts and bruises to the face.
The attack happened at midnight outside the club on Breck Road.
Det Sgt Irving said: “A man has punched the victim causing him to hit the ground, he has then stamped on his head.
“The victim was unconscious and suffered serious cuts to his head and cheek, he was then taken to the hospital.” He was allowed home yesterday after being kept in hospital overnight for observation.
A 35-year-old man was arrested and has been remanded in custody, pending further questioning.
Police are appealing for anyone who might have been in the area for either attack to contact them on 101.
