"My email account has been hacked for the second time this week. I'm gonna lodge a complaint with the cyber cell as its a criminal offence," Arbaaz posted on the microblogging site Twitter.
"Hackers don't seem to realise that such an act can land them in jail. The offense carries a 3 year jail term. Wonder if all this is worth it," he added.
Arbaaz has been riding high on the success of his debut production "Dabangg", which featured his brother Salman Khan and marked the debut of actress Sonakshi Sinha.
Now he is set to make a sequel to the film, which he will direct.
