Police on Thursday registered a First Information Report (FIR) against Regent Plaza hotel's owners and management, said SSP South Saqib Ismail Memon.

The case was registered after an inquiry report regarding the incident was completed and submitted to Chief Minister Sindh Murad Ali Shah.

The FIR was registered at Saddar police station citing criminal negligence, carelessness and not following the security plan in place for emergency situations.

The senior police official further stated in the inquiry report that the management of the hotel not only failed to follow the security plan, but also failed to inform emergency services in a timely manner.

At least 12 people were killed and 75 others injured when a huge fire erupted at Karachi's Regent Plaza hotel earlier this week.

The blaze broke out in the kitchen located at the ground floor of the four-star hotel located on the city's Shahrah-i-Faisal, and swept through the building, trapping scores of hotel guests in their rooms.

The firefighters were able to contain the blaze after three hours.
