Ghaziabad: Software engineer Sumit Kumar, who allegedly killed his wife and three children here last week, has been arrested from Karnataka, police said on Wednesday.
Ghaziabad Police with the help of Udipi Police arrested Kumar on Tuesday night. The latter have deployed three teams to nab him.
On the intervening night of Saturday and Sunday, Kumar allegedly served sedative-laced drinks to his wife Anshu Bala (32), son Prathimesh (5), daughter Akriti and son Arav (twins aged 4 years) and then slit their throats, police had said.
The bodies were found 22 hours after the incident on Sunday, following a video posted by Kumar on his family WhatsApp group, in which he admitted to the killings.
Kumar had said in the video that he would commit suicide and had purchased poison.
After being alerted, police recovered the bodies from Kumar's flat and sent them for post-mortem.
"We will produce Kumar before the media later, in the day", maintained City SP Shlok Kumar.
It was initially suspected that Kumar had purchased potassium cyanide from a medical store in Gyan Khand. However, medical store owner Mukesh, who was arrested on Monday, denied that he had sold potassium cyanide to Kumar. Mukesh had claimed that he charged Kumar for cyanide but gave him some other sedative.
A thorough search was launched by the drugs department at the medical store but cyanide was not found.
Kumar was a drug addict and had often purchased drugs for his personal use. Due to this addiction, he faced a financial crisis and lost his job in December last year.
Kumar, a native of Jamshedpur in Jharkhand, married Anshu Bala in 2011.
