Police in the city say they also took statements from six people who had witnessed crimes.

Emergency services are based at the Shekinah Mission near Union Street in a bid to take the pressure off Derriford Hospital and improve detection rates.

It will be staffed on Friday and Saturday nights with police officers, a paramedic and ambulance crew.

Trial run

It allows trained health staff to treat injuries on the spot and assess whether further hospital treatment is needed.

Victims of crime can also gain instant access to officers allowing offences to be investigated much more quickly.

Members of the charity Victim Support are also on hand to offer their services if wanted.
