The National Human Rights Commission (NHRC) Monday sent notices to the centre and the Delhi government over an incident in which a labourer died while cleaning a sewer in the city's Jahangirpuri area.

Dooman Ray, 32, a native of Katihar in Bihar, died while cleaning a Delhi Jal Board sewer on Sunday. He was taken to the Max Hospital in Shalimar Bagh, where doctors declared him brought dead.

"The notices have been sent to the Delhi's chief secretary and to the Ministry of Housing and Urban Affairs, and the response is expected in four weeks," a spokesperson of the NHRC said.

Police got to know about the incident on Sunday at around 7.30 am. They were told that Mr Ray was brought dead from the Delhi Jal Board Pump House in Jahangirpuri, Additional Deputy Commissioner of Police (northwest) AK Lal had said.
