Sisters Attacked On Beach
Police are investigating after two teenage sisters were assaulted by a group of men and women on Bournemouth beach.
The attack happened between 5pm and 5.30pm on Thursday, 2 June 2011, near the Pier and Oceanarium.
The girls aged 13 and 16 were left with minor injuries.
Police Constable Lee Mather, of Bournemouth police, said:
"The sisters were playing Frisbee with a large group of men and women when some of the women started acting aggressively toward them.
"This escalated until the two girls were assaulted."
There were around 15 or 20 people in the group. They were all of South East Asian appearance and aged around 19 or 20.
One of the women responsible is of a slim build. She was wearing a black bikini and a cream top at the time of the incident.
One of the men responsible is of a large build and was wearing a black peaked cap and possibly a white top.
PC Mather continued:
"I am appealing for anyone who witnessed this assault, and anyone with any information about those responsible, to contact me urgently.
"All calls will be treated in the strictest of confidence."
