Bocking is the executive vice president of BlackBerry and head of the messenger service. He is the latest amongst high-profile executives to leave the sinking smartphone manufacturer.
BlackBerry has declined to give out the reason behind Bocking’s departure, only noting that it was his decision.
BBM was recently made available to third-party devices and raked in 10 million downloads within the first 24 hours.
The report said that head of global enterprise solutions, John Sims, would oversee the BBM group, which will remain intact as a unit.
