Two more teenagers have been arrested on suspicion of GBH after a man was hospitalised in an assault.

Hertfordshire Constabulary said there was a clash involving a group of males, who police believe knew each other, in Gadebridge Park, Hemel Hempstead.

A 19-year-old man was taken to hospital with a head injury after being attacked at around 2pm on March 3, and is now recovering at home.

After police launched an investigation, a 16-year-old was arrested on suspicion of assault GBH and violent disorder during the early hours of the next day.

On Sunday (March 12), two males, aged 18 and 17, were also arrested on suspicion of the same offences.

All three have been released on bail while investigations continue.

After the attack, Hertfordshire Constabulary could not confirm whether the man was stabbed as they were "still working to establish how the injuries were caused at this time".
