A woman tried to snatch a baby in a buggy from its mother, police have said.
The mother, aged 30, was chatting to relatives on an Edinburgh street when another woman took hold of the buggy handles and tried to push it away. As the brakes were on she could not move it and the baby girl's parent quickly grabbed it back.
The suspect then ran off along Montgomery Street towards Easter Road where she met another woman.
The five-month old infant was not injured but the mother was left "shaken".
Police appealed for information about the incident, which happened on Montgomery Street near the junction with Windsor Street, at around 4.30pm on Tuesday afternoon.
A Lothian and Borders Police spokesman said: "Fortunately the child was not injured in this incident, although it has left her mother understandably shaken.
"They had stopped on Montgomery Street to say goodbye to some relatives, and as such we have a good description available of the woman who grabbed the buggy.
"We are very concerned about her behaviour and there is a suggestion from witnesses that the women may have mental health problems. We are appealing to anyone who may have been in the area at the time, who saw what happened, to contact us on 0131 311 3131."
The suspect is described as being aged between 18-20 and was of slight build with a pale complexion and yellowing teeth.
She had bright piercing blue eyes, shoulder-length black/dark hair, spoke with a local accent and wore no make-up. She was wearing a white hooded top with navy or royal blue leggings.
