Delhi BJP leaders, including Tiwari, had alleged "misbehaviour and attack" by AAP legislators and "anti social elements" at Kejriwal's official residence on January 30, when they had gone there for a discussion to find a way to provide relief to traders affected by the sealing drive in the city.
In his letter to Home Minister Rajnath Singh, Tiwari said he has a 'Y' category security cover, but it proved inadequate in wake of the recent incidents.
He mentioned his visits to other states for "campaigning and expansion" of the party and requested Singh for providing 'Z' category security.
The 'Z' category security detail entails 20-25 commandos covering a protectee. The cover extends to residence of the protectee who is also provided a pilot and an escort vehicle.
Tiwari, an MP from North East Delhi, lives at North Avenue.
