A 33-year-old man is in a serious condition in hospital after a second stabbing in 24 hours in Cardiff.

He was attacked in the early hours of Saturday morning in Loudoun Square in the Butetown area of the city and is in Cardiff's University Hospital of Wales.

The first stabbing was on Friday morning at Smeaton Street in Riverside and a man is stable in hospital.

South Wales Police have issued a 24-hour notice of stop and search orders in three inner city areas of Cardiff.

The force said the notice - until 1400 GMT on Sunday - will apply in Butetown, Grangetown and Riverside to "prevent serious violence".

Officers say the two incidents - which happened within two miles of each other - are not linked but they are appealing for witnesses.

Friday's knife attack in Riverside was around the morning rush hour at 07:30 GMT while Saturday's stabbing in Butetown was at about at 02:20 GMT.
