A letter in this regard was sent to Union Home minister Rajnath Singh by state Chief Minister Pinarayi Vijayan today.
He said there had been reports from the beginning that the police probe in this regard was not effective.
"The Home minister should sincerely intervene in the matter so as to raise the confidence of Delhi Malayalee community in the national capital," he said.
Rajat Menon, a class IX student, was found dead after a scuffle with a group of teenagers near his house in east Delhi's Mayur Vihar area on June 30.
