Dominica's former attorney general has been arrested on suspicion of conspiring with others to fraudulently obtain and sell passports.

Bernard Wiltshire was being held Tuesday on $18,000 bail.

Police accuse Wiltshire and three other people of selling passports to illegal immigrants, mostly from Arab countries.

It is unclear if Wiltshire has an attorney. He earlier filed a civil lawsuit against police and the government accusing them of false imprisonment and arrest after he was detained last year without any charges as police investigated the case.

Wiltshire served as attorney general from 2000 to 2002.
