A man's hunt was launched after a 12-year-old girl was repeatedly sexually assaulted in a branch of Primark.
The victim was shopping with a family member in Bury when she was tempted in the clothing store in the city center, said the Greater Manchester Police (GMP).
The man "continued to follow the girl around" at the store and later tried to lift the skirt, adding strength. He released a CCTV image of a man with whom the officers want to talk.
The policeman Stephen Rain, of the Bury division of GMP, said: "It was a blatant and repeated sexual assault of a girl when she was just shopping with her family.
"We are determined to find out who committed this crime.
"We would like to ask anyone who recognizes the man in this picture or has any information, to get in touch immediately."
The girl was on the first floor of the store when a man approached her from behind and felt her around 4:30 pm on September 11, police said.
Shortly thereafter she felt her skirt rise and turned to see the same man, whom she believes had a cell phone in hand.
Added a GMP statement: The girl ran to a member of her family and told them what had happened.
"While the family member and the victim were still inside the shop, the offender reappeared and – not realizing that the girl's family member was near – tried to approach the girl again.
"The family member challenged the man, who became very agitated and quickly made the jump through the main entrance."
