A six-week-old baby was attacked during an "extremely callous" armed robbery at a shop in Sheffield, police said.
The robber wore a black coat with the hood up
A man entered the Fashion Mahal fabric shop on Wolseley Road and demanded money while threatening the owner, her daughter and the baby with a handgun.
The daughter handed over a bag of cash but the robber grabbed the baby around the neck when the shop owner raised the alarm with neighbours at the back door.
He pointed the gun at the baby before throwing her to the floor and escaping.
South Yorkshire Police have released an e-fit image of a man they want to speak to.
Det Insp Zaf Ali said it was "amazing" the baby was not seriously injured in Monday's attack.
"We are treating this incident very seriously, especially as it could have had far more serious consequences.
"We are doing everything possible to catch the offender but would appeal to anyone who knows, or thinks they may know, the offender to come forward in complete confidence.
The robber was described as white, 5ft 8in tall, of medium to chubby build and clean shaven. He was wearing a black hooded coat, with the hood up, and black trousers. He spoke with a local accent.
Police said he escaped with a "substantial" amount of cash.
