The Anuradhapura Chief Magistrate ordered a travel ban on Iron Ranasinghe alias 'SF Loku Malli', who is said to be the main suspect in the murder of night club owner Wasantha Soyza.
Soyza was murdered on the night of September 24 when a group of over 20 gangsters invaded the night club premises.
Three others were also wounded in the attack.
Police have arrested 20 individuals connected to the attack. However, SF Loku Malli is still evading arrest.
