New Delhi:  A property dealer, a milk vendor and a restaurant employee were murdered in three separate incidents in the capital, police said on Thursday.

Rakesh Kumar, 25, who ran a dairy in northeast Delhi, was stabbed to death by a milkman, Parveen, over a petty dispute.

Parveen came to Rakesh's dairy and asked him to keep his empty milk containers at the latter's shop. When Rakesh refused, an altercation took place.

"Parveen drew out a scissors and hit Rakesh on his chest. The scissors pierced through Rakesh's heart and he died on the spot," Dep-uty Commissioner of Police Jaspal Singh said.

In another incident, property dealer Salim Phelwan, 40, was gunned down when he was going on a motorcycle to his Kadampura home in northeast Delhi late Wednesday.

Police said Salim Phelwan, accused of murdering his sister in Uttar Pradesh, was shot dead in the Yamuna Vihar area by unidentified assailants. Singh said that the killing could be the fallout of a personal ven-detta.

In the third incident, 25-year-old Ramesh, was stoned to death at his rented accommodation in Dabri area of southwest Delhi Wednesday. "He and his roommates used to fight daily after consuming alcohol. We suspect they are behind the murder," said a police official.
