The father of a teenager who was allegedly gang raped and later died after being set on fire in eastern India is demanding a federal inquiry into the case.

Hundreds of people protested Friday in Kolkata, accusing West Bengal state authorities of failing to protect the family.

Police say the 16-year-old girl reported being gang raped on two consecutive days in late October.

The girl's father told reporters last week that his daughter was set alight Dec. 23 after being threatened with violence if she didn't withdraw her complaint. She died from her injuries on Wednesday. Neither she nor her father is being named by Indian media under laws guarding rape victims' identities.

Police arrested six suspects in the rape and another two who allegedly set the girl on fire.
