Baby threatened during Alvaston robbery
Police say a man who threatened to hurt an eight-week-old baby during a street robbery is "despicable".
The robber forced the baby girl's mother to hand over her purse and mobile phone in Alvaston, Derby, on Saturday afternoon.
He then pulled a ring from her finger before running from the scene at the junction of Brighton Road and Wisgreaves Road.
No-one was hurt, but police said the 21-year-old woman was left shaken.
Det Insp Mark Argyle, of Derby's robbery unit, said: "Robbery is a frightening offence anyway but it is despicable that someone would threaten to hurt a baby."
The man is described as white, 5ft 7in (1.7m) tall, of medium build and had a scarf across his face.
He was wearing a black hooded top with a white logo on the chest, dark jeans and black trainers.
Police do not believe a weapon was used during the robbery.
Any witnesses or anyone with information about the incident, which happened at 1625 GMT, should contact the Derbyshire force.
