Two occupants escaped injury after a masked man hurled a petrol bomb at a house in Sandholes, near Cookstown last night (Saturday).
It happened just before 10pm last night at Crossglebe.
Police say the petrol bomb was thrown at the front of the property.
A woman in the house heard a loud bang and saw flames at the window, and when she went to the front of the house she saw a masked man standing next to a car parked outside.
The suspect dropped a bottle he had been holding and ran off.
The two occupants who were in the property at the time of the incident were uninjured.
Police are working to establish a motive for the attack and would also like to hear from anyone with information. They are particularly keen to hear from anyone who was in the area and who have seen a man fleeing the scene.
Detectives can be contacted by calling 101, quoting reference 1908 20/02/21.
