“This was a distressing incident, and I encourage witnesses or anyone with information about what happened to come forward and report it to us.

“A decision has been made to issue a further Section 60 order, which reflects the seriousness of the incident and the investigation.

“It is a decision which has not been taken lightly, and is a short-term measure aimed at targeting and disrupting these incidents.

“The order will remain in place for the next 24 hours.

“Meanwhile we continue to respond to peoples’ concerns about anti-social behaviour from a small group of young people in and around the Worthing area.

“We are working closely with our partners, including Worthing District Council and key partners in Children’s Services to address these issues and keep our communities safe.”

The section 60 order gives police officers extra powers to search anyone and seize any weapons found in Worthing town centre, without grounds, to prevent further incidents taking place.
