A man who tried to rob a Baltimore County bank yesterday was foiled by an exploding dye pack but then robbed an Ellicott City bank half an hour later, before Howard County police arrested him.
The police said Douglas Andrew Tully, 28, of Severna Park confessed to robbing those two banks, another Howard County bank Wednesday and another Baltimore County bank the previous Monday.
A man fitting Mr. Tully's description entered the First National Bank in the Ingleside Shopping Center on Ingleside Avenue and Route 40 in Catonsville at 9:43 a.m. yesterday, handed a teller a note that said he was armed and demanded the money in her drawer, said Baltimore County police spokesman Jay Miller.
"The teller complied but also put two dye packs in," Mr. Miller said.
The man then took the canvas sack containing the money and the dye packs out of the bank, where the packs exploded.
He dropped the sack and ran. The money was recovered, and police got a description of the man's car from a witness, Mr. Miller said.
A man fitting the same description, which included several bandages on his face, held up a Signet Bank on Route 40 in Ellicott City a little more than 30 minutes later, said Sgt. Gary Gardner of the Howard County police.
The man gave the teller a note similar to the one used in the Catonsville robbery, saying he had a weapon and demanding cash.
He ran out the front door of the bank with about $700, Sergeant Gardner said.
A bank employee told Howard County police the man drove away in a blue car but did not know the model.
But police dispatchers told patrol officers to look for a blue Subaru after receiving a vehicle description from a regional broadcast by Baltimore County police.
A Howard County police officer saw a car matching the description of the car used in both robberies headed east on Interstate 70 toward Baltimore and made a traffic stop.
Employees from the Signet Bank in Ellicott City were brought to the scene where they identified the man as the one who robbed the bank.
When officers searched the car, they found the money taken in the Ellicott City robbery.
Police arrested Mr. Tully, and when officers later questioned him, he confessed to both robberies yesterday, according to a court document.
He also confessed to robbing a Signet Bank branch in Baltimore County on July 1 and another Signet Bank on Route 1 in Jessup in Howard County on July 3.
Mr. Tully was charged yesterday in Howard County with two counts of armed robbery.
He was being held on $250,000 bond at the Howard County Detention Center, police said.
Baltimore County police said Mr. Tully is a suspect in both robberies there and could be charged later this week.
