A CRIMELORD arrested for last weekend's armed cash-in-transit heist is suspected of being involved in a spate of similar crimes including an armed robbery earlier this year.
The gangster, aged in his 40s, and three other people remain in custody today over the security van heist in Walkinstown on Saturday afternoon.
The fourth suspect was arrested in the Tallaght area yesterday afternoon.
Meanwhile, it has emerged that a criminal who was sent to prison on Saturday has been arrested by gardai investigating an armed robbery that took place the previous day.
The Crumlin man, who is in his 20s, was taken out of prison yesterday for questioning about an armed raid on a post office at Bunting Road in Walkinstown, on Friday morning.
He had been sent to prison on Saturday for an unrelated crime.
He was taken from the jail yesterday by detectives investigating the raid, in which two men, armed with a shotgun and a hammer, held up staff and threatened customers. One raider fired into a glass panel, injuring a female employee who was struck by glass in the face.
The man was taken to Terenure garda station and was still being held there today.
A week earlier, raiders took €16,000 from the same post office and gardai suspect that members of the same gang were involved in both robberies.
