GRANTS PASS, Ore. -- A man with a sawed-off shotgun just marched into a bank on the north end of town, the caller told 911.

Meanwhile, a man with a handgun walked into a bank on the southside of town and fired two shots into the ceiling.

The first call was a fake. The bullets were real, however: the robber made off with $12,000 and stayed at large for more than a year.

Police in Grants Pass said Thursday that two men are now in custody, one accused of calling in a fake 911 call, the other charged with robbing the bank at gunpoint.

But before the investigation could wrap up, officers found themselves face-to-face with live grenades and blasting caps.

"This one," said Sgt. Det. Dennis Ward with the Grass Pass Department of Public Safety, "had a little bit of everything."

You can run, but you can't hide

Calling in a fake 911 call isn't exactly the work of super criminals.

"It's a pretty common ploy to call something in on the other end of town," Ward said.

Even as the false report said go north, Ward and other officers responded to the Umpqua Bank. A man strode in brandishing a firearm, then shot at least two rounds into the ceiling.

Police searched the area, but the culprit slipped away.

That was Jan. 18, 2008.

On March 26, 2009, police from Grants Pass knocked on a door in Castaic, Calif., with a little help from the Los Angeles and Kern county sheriff's offices, the FBI and the U.S. Marshall's Office.

Robert Alan Peters, 45, is now in the Los Angeles Jail, charged with robbery and aggravated theft in Grants Pass -- and warrants out of the LA area.

Grenades and guns

With the suspected triggerman in custody, detectives turned to the fake 911 call. Investigators suspected Anthony George Arrigo made the call and supplied the firearm used in the robbery.

On Wednesday night, Grants Pass, Josephine County and federal law enforcement served a warrant at Arrigo's Grants Pass reisdence. Arrigo, 55, was arrested on suspicion of robbery and aggravated theft.

While searching Arrigo's house, detectives came across three devices that appeared to be grenades and blasting caps.

Investigators evacuated the house, and the Oregon State Police Bomb Squad was called to the scene to remove the items.

Detectives resumed the search of the house, locating a firearm believed to have been used in the robbery. The OSP Bomb Squad will determine whether criminal charges are possible based on the grenades and blasting caps.
