Two young girls were approach by men in Lambeth in separate incidents that the police are treating as attempted abductions.
The first incident happened just before 8am on Tuesday, 21 March when a man approached an 11-year-old girl waiting for a bus near the Crown and Sceptre pub on Streatham Hill.
The man asked the girl if she wanted to get into a car. She said no and managed to get away by boarding a bus.
A second attempted abduction happened on around 8am on Wednesday, 22 March near the entrance to Archbishop Park on Lambeth Road.
A man approached a 13-year-old girl and tried to drag her into the park. A dog walker is reported to have shouted at the man which allowed the girl to escape his grip and run home.
Detectives from Lambeth CID say it’s possible that the two incidents are linked and are appealing for anyone who has information about these incidents to come forward.
