A key weapon in the battle to stop bank robberies worked as it should yesterday.
In Timonium, a special dye pack placed with the loot given a holdup man exploded and the fleeing robber threw away his swag, just as he was supposed to. One problem: The discarded loot landed atop a ventilation duct back into the bank.
Within minutes, tear gas from the exploding dye pack filtered into the Chase Bank of Maryland, in the 2000 block of York Road, and employees began complaining of swollen eyes and skin irritation.
Paramedics were called, and the bank was evacuated while those whose eyes were burning from the gas were treated. Exhaust fans were set up inside to air out the bank.
Meanwhile, the robber struck again.
A half-hour after the 10:15 a.m. Timonium holdup, a man answering the same description robbed the Mercantile-Safe Deposit & Trust Co. branch in the 7000 block of Security Boulevard near Woodlawn, Baltimore County police said.
Having been burned once, the gunman this time warned the teller: "No dye packs."
The teller complied, and a suspect described as being about 6 feet tall escaped with an undisclosed amount of cash and no tear-gas canister. He was last seen wearing faded blue jeans and jacket and a baseball cap.
