A MAN impersonating a police officer has been arrested on suspicion of kidnap.

A 14-year-old girl was walking to school in Crawley when she was approached by a man wearing a yellow high-visibility jacket at 8am on Wednesday.

Police say the man took the girl to an adjacent area off the road in the Three Bridges area and searched her clothing before cycling off.

A 32-year-old local man was detained in Crawley at 11.15am the following day.

He was arrested on suspicion of kidnap and impersonating a police officer.

The man is currently in custody for interview and further enquiries.

Superintendent Marc Clothier said the girl is “safe and unharmed”, and is receiving support from officers, who are working with her family.

"We understand that this arrest will impact communities,” he said.

“We want to reassure people we have not received any similar reports at this time and there is no current risk to anyone in the community in relation to this case.

“You will see more uniformed patrols in the area, and we encourage you to stop and talk to us if you have any concerns.”

Sussex Police also gave advice how to identify a police officer.

“We understand some people may want additional reassurance when interacting with a lone police officer and when you are alone,” Supt Clothier said.

“If this is the case, genuine officers can use their police radio on loudspeaker to talk to the operator in the police control room.

“The operator can confirm the identity of the officer, that they are on duty and carrying out legitimate policing business.

“You can also ask a passer-by to observe. Off-duty officers intervening in a crime in action or where someone is vulnerable, and not carrying a radio, will quickly call 999 for back up.”

He added: "If you do see any behaviour that causes you concern, please always call 999 right away.”

Anyone with information that may assist in the investigation is urged to call 101, quoting Operation Lonsdale.
