A pregnant woman and her young child were taken to hospital after a hit-and-run crash in St Annes.
Police are hunting for a truck driver they say drove past a stop sign and hurtled into a black BMW before fleeing the scene.
Both vehicles smashed into a garden wall, which was demolished in the collision at around 11am on Friday.
The Transit recovery truck, which had been travelling along St Andrew’s Road South, away from the town centre, and the car were both badly damaged.
The 27-year-old driver of the BMW, which was travelling along St Thomas’ Road towards Clifton Drive South, and her child were both taken to Blackpool Victoria Hospital. The woman suffered leg and internal injuries.
PC Adam Lloyd, of the Road Policing Unit, said: “We urgently need to speak to the driver of the recovery truck so we can get his version of events and urge him if he sees this appeal, to get in touch. Fortunately the pregnant woman wasn’t seriously injured in the collision, but the recovery truck driver could not have known this for sure when he left the scene.”
Call police on 101 with information.
