Police investigations into the attack on the Leader Publications press have so far drawn a blank with the investigators unable to make any headway.

OIC Mount Lavinia Police Mahesh Perera however told The Sunday Leader that investigations were being conducted by several police teams.

A day after the attack there was a chance of a breakthrough when one of the witnesses had identified a person believed to be involved in the attack on The Leader press last Wednesday.

However, OIC Perera said the police found out that the said person was in the Welikada prison for a long time.

"We found out that the person identified by the witness is in the Welikada prison. He has been in prison for a long time," he said.

Media Minister Anura Priyadharshana Yapa told The Sunday Leader that he had enquired about the progress of the investigations and found that statements had been recorded from 12 persons.

"That is all what I got to know. However, the investigations are still continuing," he said.

Police Spokesperson Senior DIG Jayantha Wickremaratne told The Sunday Leader that the police had so far not got any lead on the investigations.

"Fifteen persons, including a couple of persons who were with a container near the premises were questioned. No one has been taken into custody," he said.
