The police, which had initially dubbed the case as arising of "road rage", later said the matter appeared to be a "conspiracy", as claimed by Tiwari, who is also the Delhi unit chief of the BJP.
The incident occurred around 1.30 AM when Tiwari's staffers were in a vehicle which brushed past the duo's car while taking a turn near the MP's residence in Lutyen's Delhi, police officials said.
Once inside the premises, they roughed up three of his staff members using the rods and the sticks, even as the act was being captured in a CCTV camera there, a senior police official said.
One of the staff members informed the police, which son rushed to the spot and held the two main suspects.
On the basis of the CCTV footage police are trying to find the other accused, said the officer.
"My residence at 159 North Avenue has been ransacked by 8 to 9 people," he tweeted.
"It looks like a conspiracy and the police are involved in it. No one should be spared," Tiwari said.
Tiwari's aides claimed that the group, which had entered the bungalow through the gate meant for public entry, also abused them while demanding to see Tiwari, who was not at home then.
A couple of hours after Tiwari's allegation, the Delhi Police said the matter appeared to be a "conspiracy".
Following the attack, the BJP leader has demanded better security from the police.
Mukesh Kumar Meena, special commissioner of police, New Delhi range, also said the incident does not appear to be a case of simple road rage.
"An accident happened initially. It's not a case of simple road rage. The attackers collected in an organised way with rods and sticks and then trespassed into the MP's house," he added.
The officer said the FIR has sections of rioting, trespass and attempt to commit culpable homicide.
The police, meanwhile, have arrested the two brothers and are questioning them to find details about the other accused.
In the CCTV footage, apart from the duo, there are other people who could be seen running amok with rods and sticks, police said.
