Mr. Bush, who was charged on 11 counts of corruption- and theft-related charges last month and is due to appear in court Friday on those charges, was released from police bail Tuesday and has not been re-bailed to return for further questioning in the explosives investigation, according to the Royal Cayman Islands Police Service.
The ex-premier complied with earlier police bail conditions when he reported back to anti-corruption police officers Tuesday morning.
Businessmen Suresh Prasad, who was arrested on the same day as Mr. Bush in December in relation to the explosives importation investigation and answered his bail conditions Tuesday morning, has also been released from police bail.
Neither man has been charged with any offences relating to the explosives importation probe.
However, police said the investigation into the circumstances surrounding the importation of explosive substances without valid permits, on or before February 2012, was still ongoing.
Mr. Bush last month was formally charged with two counts of misconduct in a public Office, four counts of breach of trust by a member of the Legislative Assembly, contrary to section 13 of the Anti-Corruption Law 2008, and five counts of theft, contrary to section 241 of the Penal Code 2007 Revision.
