The police conducted flag march in northeast Delhi's Bhajanpura and Khureji Khas on Tuesday after the areas witnessed arson and stone pelting.
A battery shop was set on fire in Bhajanpura. The shop was vandalised and burnt batteries were strewn on the road.
Rakesh Kumar, a local, said the incident took place at around 3.30 pm.

'We are taking appropriate actions. The required force is being used. Tear gas and mild lathicharge has been used to control the crowd. We will detain the miscreants and appropriate action will be taken against them,' Golcha, who is the Special Commissioner of Police (Law and Order northern range), said.
'The stone pelting has currently stopped in the area. We will be here till the situation comes under control. If required, we will deploy extra force,' he added.
