On February 1, Baisala fired two rounds in the air at Shaheen Bagh, where an anti-CAA protest is under way, police said.
Kapil Baisala and his father joined the AAP in early 2019, police said. DCP (Crime Branch) Rajesh Deo said his mobile phone has been seized and they have retrieved his WhatsApp data and photos of him and his father joining the party. Baisala's police custody has been extended by two days.
In a series of tweets, BJP chief J P Nadda said people of the country and Delhi today have seen the 'dirty face' of AAP. The AAP hit back, questioning the police investigation.
The poll body also observed that the investigation had 'political connotations' and Deo's conduct has 'consequences' for 'free and fair elections'.
