The plan for the robbery was very well taken care of. The thieves (three men and a woman) had equipped themselves with coveralls that covered them from head to toe (so that one could not even understand the colour of the skin), weapons, bag where to put the money, a radio to monitor the transmissions of the police.
When they got out of the van, they headed for the bank entrance, with a firm and sure step, but when they tried to open the door, the surprise: the bank was closed to the public. They tried to push the door, with increasing nervousness, but this only served to attract the attention of the staff who were carrying out activities inside, and consequently they called the police, who promptly intervened.
The four tried to escape, trying to throw the most compromising evidence (in particular the guns) from the van, but they were reached and arrested.
