Three Men Assaulted In Portsmouth
Police have released a CCTV image after an attack in Portsmouth.
Officers tell us around eight men assaulted three other men who were carrying rucksacks and bags through Guildhall Walk.
The group followed the three men into Commercial Road just after 2am on Sunday, assaulting another man.
Officers are appealing for help to identify anyone in the CCTV image; who they say could hold vital information.
PC Darren Tombs, based at Portsmouth Central said:
"We are also keen to identify the victims of the assault. This happened in a busy area of the city as many people were leaving clubs and bars. Anyone with information is asked to come forward."
A 19-year-old man from Portsmouth has been arrested and bailed while investigations continue.
Anyone with information should contact PC Tombs at Portsmouth Central on 101.
As the evenings start getting darker, officers are urging riders to use lights and wear reflective clothing.
Isle of Wight Council bosses have overturned a vote by councillors - who had rejected the partnership to secure £900 million of funding.
The busy road's being made two lanes in both directions between Segensworth and Titchfield - it's due to take 18 months.
