BJP leaders blame Kerala police
Union Minister V Muraleedharan has blamed the state police for failing to prevent political murders in Kerala.
"It is a matter of concern that the home ministry that is handled by the chief minister himself is so inefficient," said Muraleedharan in a press release.
State BJP chief K Surendran has accused the state government of facilitating terrorists.
"The police let Alappuzha (twin political murders earlier this year) repeat in Palakkad," he said.
On Friday, after the murder, PK Usman, state general secretary of SDPI alleged that the RSS was turning Kerala into a battlefield.
"The police must conduct a proper probe to find the culprits," he said in a Facebook post.
