A fire in a thatched roof at one of Oxfordshire's popular visitor centres could have been started deliberately.

Police have not ruled out arson after part of an outbuilding at Cogges Manor Farm Museum at Witney caught light early on Saturday morning.

A passer-by saved the thatched building from a potentially major blaze by raising the alarm.

Fire crews from Witney and Eynsham arrived at around 3am and managed to prevent the fire getting out of control.

The Museum today hosts the Duke of Kent, who is on a tour of Oxfordshire.
