The jail houses 251 women prisoners.
Manju Govind Shette (45), a convict, died at government-run J J Hospital last night after allegedly being beaten up by a woman prison official, which touched off the protest.
Some women inmates climbed atop the roof of the jail while newspapers were torched inside, said a police official.
The inmates wanted to present the issue before the media which is not permissible under the prison rules, and police were trying to mediate between the agitating women and the jail staff, he said.
Akhilesh Singh, Deputy Commissioner of Police (Zone-III), said that judicial inquiry into the inmate's death was underway. "We will look into the allegations against the jail staff," he added.
