Ismet Nurcin, 30, who is self-employed and an Australian permanent resident, was also jailed four weeks on a second charge for using criminal force on SATS Auxiliary officer Noor Azhary Daud, 29, on Aug 29.

The incident happened at a gate holding room at Changi Airport Terminal 1 when Ismet was waiting in transit to catch a connecting flight to Turkey.

A Community Court heard that Ismet, who pleaded guilty to two charges, had offered a bar of chocolate to Mr Noor Azhary who declined.

When asked for his passport and boarding pass, Ismet did not answer and said that he was having some family problems.

He was then seen walking and talking to passengers.

About 10 minutes later, when Mr Noor Azhary asked him if he was travelling on the Turkish flight, Ismet responded, 'No, the aircraft is going to explode.'

Several other passengers also heard him say this.

When Mr Azhary tried to calm him, Ismet threatened to 'get'' him, and also pushed the officer on the shoulders and scratched his right hand.

Ismet's lawyer S.S. Dhillon said his client, a father of five, was suffering from substance-induced psychoses at the time of the offence.

Ismet had taken various drugs in Perth two days before his flight to Singapore, the court heard.
