Tonga's police commander says he cannot reveal the identity of a man arrested in a drug sweep yesterday.
After receiving information from the Australian Federal police, Tonga police conducted a series of searches for illicit drugs.
At the same time Australian police executed search warrants in Sydney.
The police commander in Nuku'alofa, Chris Kelley, won't say what sort of drugs are involved nor reveal the identity of the arrested man, who's facing firearms charges.
He says more arrests are possible.
