Kolkata/IBNS: A team of three Central Bureau of Investigation (CBI) officers on Thursday reached the residence and noursinghome of Trinamool Congress MLA Sudipto Roy for quizzing in connection with the rape-murder of a 31-year-old junior doctor at Kolkata's RG Kar Medical College and Hospital.

Roy, who is an MLA from Sreerampur, had reached RG Kar Hospital after the crime was discovered.

The TMC leader is also the president of West Bengal Medical Council president and he also heads the association of patients' welfare at RG Kar Hospital.

Though the RG Kar case is now being probed by the CBI, the state administration is facing public anger over its slow progress in the case until it was handed over to the premier investigating agency under the central government.

One person, a civic volunteer, has been arrested in connection with the case but protesting students as well as the victim's parents suspect more people are involved in the case.

Former RG Kar Medical College and Hospital principal Sandip Ghosh was arrested by the CBI in a case pertaining to the financial irregularities at the state-run hospital.
