Jakarta – An Indonesian court sentenced a grandson of former President Suharto to two months and 22 days in jail on Thursday for illegal firearms possession, but he could be freed within a week because of time already spent in detention.

The sentence was below the one year imprisonment demanded by prosecutors for Ari Haryo Wibowo, popularly known as Ari Sigit. The maximum penalty for the charge was death. "The panel of judges, led by chief judge Herri Suwantoro, gave the defendant Ari Sigit a sentence of two months and 22 days in jail," Central Jakarta Court clerk Andi Syam told Reuters.

Ari Sigit's lawyer, Juan Felix Tampubolon, told Reuters if neither side appealed against the decision within one week then his client would go free because he had been in detention since August.

Ari Sigit was detained when police found 70 live bullets stashed in his Jakarta house during a search for his fugitive uncle, Hutomo "Tommy" Mandala Putra. Tommy has since been caught by police and is being investigated over the murder of a Supreme Court judge who sentenced him to graft last year – keeping the once mighty Suharto family in the headlines. Ari Sigit had previously denied any wrongdoing over the weapons charge.

The Suharto family has been the focus of several graft probes since the former general stepped down amid social chaos in 1998. The former President Suharto is in hospital suffering acute pneumonia that has been compounded by other ailments, such as diabetes.

Ari Sigit's wife was jailed for illegal drugs possession last year. She has since been released.

Critics accuse Suharto and his six children of corruptly amassing up to $45 billion during his 32-year rule. All the Suhartos have denied any wrongdoing.
