New Delhi, Jan 28 (Agencies): A 40 year old steel trader with injury marks was found dead under the Naraina flyover in west Delhi, police said on Friday.

The body of the deceased Praveen Singh was found by his family on late Thursday.

"He did not return home till late Thursday from his shop in Naraina. His family members went looking for him at his shop in the same locality and found the body close to the flyover," said a senior police official.

The trader's brother added: "Praveen usually returns by 9 p.m. in the night. When he did not return last night, we tried to contact him on his mobile phone."

He said they then contacted the shop to learn that Praveen had left around 9 p.m.

"We then found his body lying below the Naraina flyover road at around 10.30 p.m., as if he had been thrown from a height," added the brother.

Injury marks on the body of the deceased have also been observed.

A case of murder has been registered and investigations are on, police said.

Praveen is an uncle of Kuldeep Singh who was found murdered along with his wife Monika in Ashok Vihar in north Delhi in July last year.

The twin-murder by a close family member was labelled an instance of honour killing.

"Police are trying to find any links between the two murders. It is difficult to divulge anything at this moment," an official said.
