A second man has been charged in connection with the car bomb at Strand Road police station in Londonderry.
A 53-year-old man has been charged with a number of offences including possession of firearms and ammunition with intent to endanger life and possession of a prohibited weapon.
He is due to appear at court in Derry on Monday.
A 42-year-old man appeared in court on Friday charged with bombing the police station on 3 August.
The 53-year-old has also been charged with possession of firearms and ammunition in suspicious circumstances, and two counts of possession of imitation firearms with intent to cause fear.
A taxi was hijacked and packed with 200lbs of homemade explosives during the incident earlier this month in which no-one was hurt.
The driver was ordered at gunpoint to leave the car at Strand Road police station.
An organisation calling itself Oglaigh na hEireann claimed it was behind the attack, which badly damaged a number of businesses.
