THREE schoolboys who went to make deposits in the bank got back to school later than expected. But their excuse made a story straight out of an action thriller. The lads happened to be in the bank when a raider demanded $100,000 and threatened to set the bank on fire. The boys joined in the chase and overpowered the man. The young heroes said they were not worried about their safety - they just felt they had to do their duty. In the meantime, swimmers were on maximum alert after two people were attacked and killed by a shark near Silverstrand Beach. Shark fears did not, however, dampen enthusiasm at the dragon boat races.
