Two teenagers have been arrested after a 14-year-old girl was attacked and sexually assaulted in a park in Abingdon in Oxfordshire.
Police said the girl was subjected to a serious sexual assault in Albert Park at about midnight on Friday.
Hours later a 16-year-old boy was arrested and on Sunday officers arrested a 17-year-old man.
A section of the park was cordoned off on Saturday while forensic officers examined the area.
Both youths have been released on bail pending further inquiries.
Police have urged anyone with any information to contact them.
