Members of a gang of safecrackers tried to break into the vault at the Banco Cathay in Alajuela early Tuesday, but their torch set off fire alarms that resulted in the arrival of the tactical squad of the Judicial Investigating Organization.
The pair, who were recorded on film, appear to have come in through the roof and used an acetylene torch to burn their way to the vault.
The pair managed to flee before agents entered the bank, but they left behind their tools.
A handful of businesses have been victims of similar crooks.
In another burglary case, a 27-year-old man was apprehended inside La Casa de los Azulejos y Pisos Cerámicos in Los Sauces, San Francisco de Dos Ríos. He also is believed to have entered through the roof. He was facing action in the Juzgado Penal de San José.
