Armed police responded to an incident in the town centre this afternoon (Tuesday).
Officers received a report of concern for the welfare of a woman in her twenties who was acting in a ‘disruptive manner’ at around 12.30pm in Terminus Road.
Police, accompanied by armed officers who had been in the area at the time, located the woman a short while later and safely restrained her.
A Sussex Police spokesperson said nobody was hurt and arrangements are being made for the woman to receive welfare support.
They added, “Firearms were not deployed.”
