Detectives want to speak to a man after a woman was sexually attacked in the street.
The victim was on her own after she lost her friends during a night out.
She had been to a few bars by herself when she started talking to an unknown man outside the Star and Garter pub in Portland Street, Hull city centre.
The man is one of 13 people police want to trace in this month's edition of Caught on Camera.
Detective Constable Justin Marrow, of Hull's priority crime team, said: "The victim was on a night out and became separated from her friends and visited a few public houses on her own.
"She was standing outside the Star and Garter public house and became engaged in conversation by an unknown male.
"The police would like to talk to the male pictured in order to assist them with their enquiries."
The assault happened at 4.40am on Saturday, August 2.
Police are also hoping members of the public can identify a man who coerced an elderly man, who suffers from dementia, into handing over £280 cash.
The suspect, pictured in ref 306, was in The Griffin, in Anlaby Road, west Hull, on July 30, when he stated talking to the victim.
Before long, the elderly man had handed over a wad of cash to the man in exchange for fake money.
Det Con Marrow said: "This was a cruel crime against a vulnerable person.
"The elderly victim, who suffers from dementia, was in the public house and was approached by an unknown male who engaged him in conversation.
"The victim was subsequently coerced into parting with his money to purchase counterfeit notes."
Detectives have also released images of a man who headbutted a security guard in Sainsbury's, in Princes Avenue, after shop assistants refused to serve him alcohol.
Two women are also wanted for pretending to help a drunk man who had fallen off his bike, only to steal his rucksack and his bicycle.
A man is wanted for common assault and battery after getting out of his car and on to a parked bus and head- butting the driver.
Det Con Marrow said: "We need the help of Mail readers to try to find out who is responsible for these crimes, which may otherwise go unsolved.
"If anybody recognises somebody in the pictures, I would ask that they get in touch with police."
