A woman has been arrested after she allegedly opened fire on emergency workers responding to a motor vehicle crash in Dieppe, N.B., on Saturday afternoon, police said.

According to an RCMP news release, a car went off the road on Adélard-Savoie Boulevard, about a half kilometre from the Moncton airport at approximately 2:30 p.m.

When firefighters, paramedics and police responded to the scene, the woman fired shots at them, according to the RCMP.

None of the emergency workers were injured. Several streets were then closed to traffic to "ensure the safety of first responders."

After about 45 minutes, the woman was taken into police custody and taken to hospital for treatment of injuries sustained during her arrest. Police have not released any details about the extent of the woman's injuries, or whether she's still in hospital.

Police would not say how many shots were fired during the incident on Saturday. (Submitted)
