An investigation has been launched over the circumstances which led to bail being granted to nine suspects arrested over the Easter Sunday attacks.
The investigation is being conducted by the Police Special Investigations Unit (SPIU).
The nine suspects arrested from the Wellampitiya copper factory over the Easter Sunday attacks were granted bail this week.
In granting bail, the court said that the Wellampitiya Police had failed to mention the offences the suspects were alleged to have committed.
The copper factory was linked to two of the Easter Sunday suicide bombers.
