A GUNMAN who shot two police officers investigating an execution-style killing is believed to have tried to take his own life.

The 28-year-old Huddersfield man was discovered with a serious gun shot wound to his head in the Northowram area of Halifax at about 7.30pm yesterday.

Police found the man in the driver's seat of a P-registration red Peugeot 106 in Hall Lane.

The car contained a firearm.

The man, who has not been named, had previously gunned down two police officers in The Fleece pub on Elland Road in Ripponden at 4.10pm yesterday.

The gunman, who opened fire in the busy pub when four officers arrived to arrest him for questioning, is now in a critical condition under police guard in Bradford Royal Infirmary.

The officers were investigating the murder of Zubair Munir, 20.

Det Supt Paul Kennedy said: "We believe that there is a connection between what happened last night and the shooting of Mr Munir.

"I would appeal to anyone who may have seen or spoken to the man between him leaving the public house and the car being found about seven miles away in Northowram to get in touch with us."

He also urged anyone who may have seen the car in the last few days to come forward. The car registration number is P689 UWW.
