Manipur chief minister O Ibobi Singh has urged his Karnataka counterpart DV Sadananda Gowda to expedite investigation into the mysterious death of Manipuri student in a Bangalore college hostel last month, official sources said on Sunday.

Singh had asked Gowda to personally look into the matter on the sidelines of the chief ministers' meeting on National Counter Terrorism Centre (NCTC) at New Delhi on Friday.

Gowda assured Singh that all steps would be taken by his government to probe the death of Richard Loitam (19), a second year student of architecture at a private college in Bangalore on April 19.

There has been protests against the incident by students and social organisations in Manipur in the past two weeks. Protest rallies were held in Bangalore and in New Delhi to seek justice for Loitam.

Official sources on Sunday said senior superintendent of Police P Dhanakumar has reached Bangalore to probe the matter jointly with the Karnataka Police.
