According to police, two men were involved in the attack. One was on board the bus as an accomplice and the other threw the grenade into the bus. The man outside the bus was known to the driver.
“It seems to be a case of revenge between two families,” said the subcommander of the Bogota Metropolitan Police, Colonel Gildardo Pico.
An initial investigation indicates there that the man who threw the grenade had served time in jail for murder, after being informed on by the bus driver’s brother.
The man who tipped off police about the perpetrator’s motive is currently being held in Bogota’s Modelo jail, while police investigate his part in the murder of the grenade-thrower’s brother.
Police believed that the man who died in the attack, identified as Jorge Eliecer Piñeros, was an innocent bystander.
The attack occured in the southern Bogota San Cristobal neighborhood on Monday night.
