The police on Saturday said it was looking for three or four "young black males" in connection with the murder of two Indian doctoral students in Louisiana State University campus at Baton Rouge on Thursday night.

Chandrasekhar Reddy Komma (31) and Krian Kumar Allam (33) were found shot dead in the apartment of Allan, the police said.

Sgt Don Kelly of Baton Rouge police department said the police are looking for "three black males" who were seen hurriedly leaving the vicinity of the apartment where the murders occurred.

"The men got into a small to mid-size four-door car, possibly occupied by a fourth person (driver)," he said.

The car, he said, was seen leaving the complex with its headlights turned out. Meanwhile, a task force comprising university police department, the Baton Rouge Police Department and the East Baton Parish Sheriff's Office has been formed to carry out the investigations.

The LSU Foundation has established the Komma & Allam Support Fund to assist the students' families.

The double murder came to light when Allam's pregnant wife sought urgent medical help from the university authorities, said Swati Badgi K Rao, Cultural Secretary of Indian Students' Association in the US.
