CONCERNING phone calls were made to a public telephone kiosk in a busy high street.

Police are investigating the calls made in Littlehampton, and fear teenagers answered the phone.

Officers want to trace anyone who may have spoken with the caller. They are not in trouble, but police want to hear from them to help the investigation.

Detective Sergeant Amanda Zinyama said: “We would really like to hear from any young people who know anything about this calls or have answered the phone to the caller. I want to emphasise that they haven’t done anything wrong and they can speak to us in confidence.”

A 51-year-old man was arrested in connection with the investigation and remains in custody. Anyone with information can report online or call 101 and quote Operation Entire.
