Police are appealing for witnesses after a woman was kicked off her push-bike on the cycle path between Dalston and Carlisle.
The assault occurred close to Dalston Sewage Works at approximately 8:15am today (June 3).
The suspect is described as a white man, medium build wearing a black coloured face mask, black hooded top and camouflage trousers.
Officers are interested in anyone who was on the cycle path this morning who may have seen a man matching this description.
Officers are particularly interested in speaking to a couple in their 50s or 60s who were walking a dog in the area in the direction of Dalston at the time of the incident.
