Rescuers looking for an Indonesian plane that lost contact after taking off from Jakarta have found suspected debris in waters north of the city, an official of the Basarnas search and rescue agency said.

Agus Haryono told Reuters it had not been confirmed that the debris came from Sriwijaya Air Flight SJ182, which lost contact after taking off with 62 people aboard.

The Sriwijaya Air plane lost contact after taking off from Jakarta, and was on its way to Pontianak in West Kalimantan province, local media have reported. Metro TV said the plane was a Boeing B737-500.

The plane was in good condition, the airline's chief executive Jefferson Irwin Jauwena told reporters. He also said the flight was delayed for 30 minutes before it could take off due to heavy rain.
