A police investigation is underway after a man was arrested by police in Lowestoft and then found to have serious head injuries and taken to hospital for treatment.

Police were called to Bevan Street West just after 8.15am yesterday where the 29-year-old man was arrested on suspicion of criminal damage and possession of cannabis.

He was brought into custody at Lowestoft police station where his behaviour and visible injuries meant police asked that he be medically assessed.

The man was later taken to the James Paget University Hospital, Gorleston, where a scan revealed an injury to his head.

He was then transferred to Addenbrooke's Hospital in Cambridge.

Yesterday's incident has been referred to the Independent Police Complaints Commission (IPCC) as a matter of course as there was police involvement prior to the man's injury being discovered.

Police have cordoned off the area where he was originally located for forensic examination and an investigation is underway into how he sustained the injury.

Anyone who may have been in the Bevan Street West area up to 8.30am yesterday morning who may have seen the man - who was wearing jeans, a T-shirt, a grey top and boots - or anyone who may have seen, or have knowledge of, any incident where he may have been injured, is asked to call Lowestoft CID on 01986 835300.

Officers are also keen to hear from anyone who may have seen the man involved in the past few days and are carrying local enquiries to trace his movements.
