A statement from the police media unit said that there were statements made that the police had delayed arresting the main suspects in the case owing to political influence.
A mother and her young daughter were found dead in their house at Kahawatte early last month and three suspects, including a woman, were taken into custody this week over the incident.
The police statement said that the Criminal Investigations Department (CID) managed to conduct the investigations successfully despite allegations there was a delay to arrest the suspects.
The police noted that investigations cannot be completed overnight and that with the arrest of the suspects the police had recovered several items connected with the crime.
“There is no truth in reports that the delay to arrest the suspects was as a result of political pressure,” the police statement said.
