On the second occasion, he was accused of attempting to cash an altered child support check.

As police investigate the case they are warning the public of check thefts as IRS refunds begin to be sent out to taxpayers.

Prosecuting Attorney Steve Alm said to not only be vigilant about tax refund checks but other payments as well.

“If you suspect that your refund check has been stolen, contact the Honolulu Police Department or the U.S. Treasury Inspector General for Tax Administration to make a report,” said Alm.
