Finance Director and spokesman for the publication group, Dushantha Basnayake, was arrested and detained under anti-terrorism laws.
International media groups described the arrest as a witch hunt By Sri Lanka authorities.
"The arrest of Dushantha Basnayake, who is close to a political adversary of President Mahinda Rajapakse, looks above all like retaliation," Paris based media watchdog RSF said in a statement.
After sacking two ministers earlier this year, President Mahinda Rajapaksa has strongly criticised Mawbima newspaper.
