A woman veterinarian whose charred body was found here was raped before being killed, police said, even as a Telangana Minister stoked a controversy asking why she had not called police immediately.

Police said four people have been arrested in connection with the rape and murder, which has sparked a national outrage.

Chief Minister K Chandrashekar Rao’s son and Municipal Administration Minister K T Rama Rao said he would “personally monitor the case.”

Congress leader Rahul Gandhi expressed shock over the incident, terming it as “terrible, unprovoked violence” beyond imagination.

The Union Home Ministry said it will send an advisory to all states to take precautionary steps to check crime against women in the wake of the murder.

Earlier, the charred body of the woman was found under a culvert on the city’s outskirts on Thursday.

Meanwhile, state Home Minister Mohammed Mahmood Ali stoked a controversy with his reported remarks that the victim should have called the police rather than her sister.
