According to official sources, the boy's father - Shripad Tukaram Mhaske (52) consumed poison late Wednesday night near the Bhagur bus stand area.
"Mhaske used to work in the bungalow of architect Shivajirao Patil, who is father-in-law of Congress corporator Hemlata Patil, located in Tilakwadi area. His son would also help out at the bungalow," maintained Inspector Ashok Bhagat of Sarkarwada police station.
"Five gold biscuits of ten tola (10 grams) each valued at Rs 15 lakh and Rs 10,000 in cash were stolen from the bungalow last month. The family noticed the theft on Tuesday and told police that they suspected Mhaske's minor son," he said.
Police investigations led to the minor son and three others, including a goldsmith, being picked up from Selu in Parbhani district on Wednesday.
