Two men are thought to have sexually assaulted a woman in a village near St Albans.

Officers from Hertfordshire Constabulary are investigating an attack which took place at around 1.30am on Sunday, June 19.

According to police, the victim - a woman in her 30s - was walking through Marford Playing Fields in Marford Road when she was approached by two males.

They are reported to have sexually assaulted the woman before running off in the direction of the River Lea.

Both men are described as being slim, having Irish accents, and wearing dark clothing.

One is described as being around 5ft 9in tall, while the other reportedly had something covering his face - potentially a bandana.

Specialist police officers are supporting the victim.
