Detectives are examining CCTV footage after a man tried to abduct a 10-year-old girl in Chelmsley Wood.
The incident happened as the girl was pushing her nine-month-old brother in his pram to a garage in Cooks Lane on Tuesday.
The man, described as aged between 25 and 30, approached the girl outside the Texaco garage at around 1110 BST.
He grabbed her wrist and the bar of the pram but the youngster kicked him and he ran off to a car parked at the nearby Big John's restaurant.
The girl was shaken but unhurt and raised the alarm at the garage.
The man is described as 6ft tall, slim to medium build and with short dark curly hair.
