Blood stains were also found at two places inside the palatial house of Pandher (60), a manufacturer and supplier of earth movers and bulldozers, said the official adding that the chemical and samples of blood stains sent for forensic examination.
Meanwhile, police today resorted to lathicharge on villagers in Nithari village who pelted stones on forces deployed there after they tried to enter the 'killer house' at about 1500 hrs by breaking the barricading put there.
The situation is said to be tense.
Yesterday the state government had ordered a high-level inquiry into the incident, fixing the responsibility of those guilty of laxity in conducting investigations, which would submit its reports in three days.
