Police and doormen in Swansea faced one of the year's busiest days

Extra patrols were put on in Cardiff, Swansea and Newport city centres for what was for many people was the last working day before Christmas.

Three forces, South Wales, Dyfed-Powys and Gwent all reported full cells.

Operation Jingle Bells, throughout December, aims to ensure people enjoy the festive period in safety.

Triage centres were set up in all three cities by safety teams to treat minor injuries.

In Newport, 50 extra officers were on patrol overnight and by 0200 GMT on Saturday 33 arrests had been made in the city for alcohol-related disorder.

Insp Rod Grindlay of Gwent Police said: "Thanks to positive proactive policing, most of the people arrested had committed low-level disorder offences and their nights were ended before they could assault anyone.

"Only six of the people we arrested had been involved in incidents where a victim was involved."

In a statement, South Wales Police said: "It was, as always, one of the busiest times of the year for Cardiff city centre police officers."

Ch Insp Steve Furnham, who is co-ordinating Operation Jingle Bells, said: "As always, we have been working closely with the licensees in relation to alcohol issues, checking that pubs and clubs are acting responsibly to ensure the safety of all those people coming into the city for Christmas parties and other celebrations."

In Swansea, at the triage centre in Castle Square, community officers handed out bottled water to revellers.
