The 42 year-old was detained in the Derry area on Saturday morning, police said.
A 200lb bomb exploded outside the station during the early hours of Tuesday morning.
Extensive damage was caused when the proxy device, which was planted in the boot of a taxi which had been hijacked at gunpoint, exploded and ripped through a number of nearby shops.
A dissident republican organisation calling itself Óglaigh na hÉireann said it was behind the attack.
