This resulted in frequent quarrels. Two days ago, Rajasekar was enraged when Purushothaman used his two-wheeler without permission. Hence when Purushotham was sleeping on the terrace of his house, Rajasekar doused him with petrol and set him alight. Purushotham ran hither and thither and subsequently fell from the first floor injuring himself and succumbing on Friday morning. Police arrested Rajasekar.
