Detectives are appealing for information after an 11-year-old girl was grabbed by a man on playing fields.
The victim had been walking home from school in Leeds on Wednesday when the man put his hand on her shoulder and asked her to go with him.
She elbowed him in the stomach, ran home and told her mother.
The incident took place while the girl was walking across playing fields between Throstle Lane and Throstle Road in Middleton shortly after 4pm.
And police are looking at whether the same man could be involved in other similar incidents later that evening.
Detective Inspector Phil Jackson, of Leeds District CID, said: “This was clearly a distressing incident for the young girl involved and we are carrying out extensive enquiries to trace this man.
“We would like to hear from anyone who was in the area and saw someone fitting his description or who has any information that could assist the investigation.
“We are aware of calls from members of the public reporting a similarly described man acting suspiciously in the area later in the evening and we are looking at whether he could be the same suspect.”
The man was described as white, between 5ft 10in and 6ft, and a bit chubby, with narrow eyes and a deep voice.
He was wearing a short red coat with a pocket on one arm, black trousers and new looking black and white Nike-type shoes. He also wore a black hat, gloves and had a dark-coloured backpack.
Det Insp Jackson said: “Officers from the local neighbourhood team are mounting increased patrols of the area to reassure the community and are also linking with local schools to offer suitable advice and support.”
Anyone with information is asked to contact Leeds District CID via 101, quoting 13170084731, or Crimestoppers anonymously on 0800 555 111.
