The police received reports that a man was walking up and down the promenade shouting, swearing and making threats towards members of the public.

The promenade was busy at that time with people enjoying the evening sunshine, the force said.

A 28-year-old man was arrested on suspicion of disorderly conduct, and, following another report to the police, he was also arrested on suspicion of indecent assault.

Anyone with information is being asked to phone the States police on 612612 or Crimestoppers on 0800 555 111.
