Police have arrested a 43-year-old man and a 17-year-old boy after two incidents in Lowestoft on Wednesday evening in which four males sustained injuries that required hospital treatment.

Officers were initially called around 6.45pm to Kirkley Fen, Southwell Road, to reports a man had been assaulted. The 52-year-old man had sustained a cut to his head and was taken to the James Paget University Hospital.

Then at about 9.25pm police received a call to an address in Grosvenor Road to reports that two males had been stabbed.

When officers arrived they found two men with visible injuries – a 21-year-old who had sustained stab wounds to both legs and a 19-year-old who had cuts to his leg, arm and shoulder. A 14-year-old boy was then found in Cleveland Road with a stab wound to his arm.

All three were taken to the James Paget University Hospital where they received stitches for their wounds. The 14-year-old and 19-year-old have both now been discharged.

Police immediately began a search of the area and the 43-year-old man and 17-year-old boy were located by officers in Tom Crisp Way and arrested.

Both are currently in custody at Lowestoft Police Station where they will be interviewed by detectives. The victims and the two arrested are believed to be known to each other.

The 52-year-old and 21-year-old remain in hospital but neither is thought to have sustained life-threatening injuries.

Police will be out in both of these areas today to talk to residents to gather witness accounts and try to provide some reassurance, while detectives work to determine exactly what happened and why.

Anyone with information about either of the incidents is asked to call Lowestoft CID on 01986 835300.
