The corpse of a baby boy was found stuffed into a toilet bowl at the girl's dormitory of a higher education institution in Bintulu, reported Berita Harian.
It was discovered at about 8am on Wednesday and officials at the institution called the Fire and Rescue Department.
They had to break the toilet bowl to remove the body, which was tightly wedged inside.
About four hours earlier, one of the students had rushed into the toilet, complaining of a stomach ache. When she did not return after a long while, her friends went looking and found her unconscious on the floor.
They also saw the body inside the toilet bowl and informed the institution's staff.
Police are now looking for a 20-year-old man, believed to be the student's boyfriend, to help in the investigation.
