Two more teenagers have been arrested after a man was left with a head injury following an assault in a Hemel Hempstead park.

An 18-year-old man and a 17-year-old boy were arrested on Sunday on suspicion of assault GBH and violent disorder, with both released on bail as enquiries continue.

The news comes after a 16-year-old boy was previously arrested on suspicion of the same offences, following the incident earlier this month.

Shortly before 2pm on Friday, March 3, officers responded to reports of an altercation involving a group of males in Gadebridge Park.

During the incident, a 19-year-old man sustained a head injury and was taken to hospital. He is continuing to recover at home.
