NATICK, Mass. (AP) — Police are looking for a man they say threatened to release a canister of gas inside a Natick bank he robbed of about $4,300 worth of foreign currency.

The MetroWest Daily News ( ) reports that authorities released more information Wednesday about the robbery Saturday at a Citizens Bank.

The FBI says the suspect told bank employees he worked for corporate security and was there to conduct an audit. They say he was inside for about 45 minutes before pulling a gun and threatening to release the gas if employees called police.

Police say he made off with euros, British pounds and Canadian dollars as well as $150 in traveler's checks.

Authorities say he is 6-foot-5 to 6-foot-6 tall, wore a black suit, tie, and a wig he said was because he had cancer.
