Dozens of people were stopped and searched after police were given special powers following a double stabbing.

Officers used the section 60 order in the Chalkwell Park area to stop 33 people but say no weapons were found.

The additional powers were put in place between 8.45pm yesterday and 6am today after two teenagers were stabbed in Chalkwell Esplanade, near to Chalkwell train station.

The stabbings happened during a large fight but police say they were able to disperse the crowd quickly.

Officers were then called to further reports of a group gathering at Chalkwell Park, where there were reports of loud music being played.

The park was closed and the group were moved on.

Additional stop-and-search powers were granted to police which allowed them to search anyone without reasonable grounds to stop them.

Though no weapons were found, one person was given a community resolution for possession of cannabis and two vehicles were seized for having no insurance.

Speaking about last night's double-stabbing, det chief insp Jim Sandford said: “I know this incident was very concerning for local residents and I would like to thank them for their ongoing support and their understanding.

“Our officers responded quickly and robustly to deal with those who felt it was acceptable to cause disorder and as a result of this action their behaviour was curtailed.

“We are continuing to support the two young victims who were injured and detectives have been working throughout the night to investigate what happened.

“Incidents like this are thankfully rare and our officers worked alongside colleagues from the British Transport Police to swiftly deal with the disorder.

“The additional stop and search powers and patrols were put in place to prevent any further crimes and it is reassuring that of those people stopped, no weapons were found and there were no arrests made.

“Officers patrolled throughout the evening and continue to do so today to ensure people feel safe and I would urge anyone with information about yesterday’s incident or any concerns to please speak to them.”

Police say they have had a number of witnesses come forward to help with their investigation into the stabbings and fight.

Anyone with information is asked to call Southend CID on 101 quoting reference 1144 of 24 July.
