Police had to close one of the roads leading to Jamia Nagar opposite the Holy Family Hospital in south Delhi after some bikers slipped on the road.

The Fire Brigade was seen responding to one such call in nearby New Friends Colony. A senior police officer said that a call of oil spill was received after which the Fire Department was informed.

“Many bikers slipped and fell on the road because of the slippery oil-like material spilled on the road. As a precautionary measure, the Fire Brigade was called and the road was washed,” one of the callers told IANS.

Further investigation is underway.
