Two men who fire-bombed a mosque following the killing of soldier Lee Rigby will be sentenced today (Friday).
Stuart Harness, 34, and Gavin Humphries, 37, made petrol bombs and threw them at the Grimsby Islamic Cultural Centre - accidentally filming the whole process on CCTV cameras they thought were turned off.
The attack happened four days after the murder of Fusilier Rigby outside Woolwich Barracks in south east London in May.
The pair threw their home-made devices at the main doors of the mosque as terrified worshippers were trapped inside.
Despite being frightened by the flames coming under the door, those inside managed to extinguish the blaze.
The mosque had been targeted earlier in the week and, because of this, two police community support officers were patrolling nearby and spotted the arson attack.
They followed Harness and Humphries and the pair were quickly arrested.
Detectives found the duo had accidentally filmed themselves making the bombs in the back yard of Harness's house in Grimsby and carrying them out of the front gate.
They had failed to spot that a CCTV system was still working.
More cameras at the mosque recorded the petrol bombs flying through the air and exploding.
All the footage was shown at a trial last month when a third man, Daniel Cressey, 25, was found guilty by a jury at Grimsby Crown Court of aiding and abetting Harness and Humphries.
Cressey drove his friends the short distance from Harness's home in Dixon Avenue to the mosque in Weelsby Road but did not take part in the arson attack.
Harness and Humphries, both of Dixon Avenue, and Cressey, of New Holland, North Lincolnshire, will be sentenced at Hull Crown Court later.
All three men are in custody.
Harness and Humphries have admitted arson, being reckless as to whether life was endangered, and Cressey was found guilty of aiding and abetting that crime.
