Ilmi, who was picked up by a team of women police personnel from her Greater Kailash residence, was brought to Parliament Street Police station for questioning, police said.
Journalist-turned politician Ashutosh, picked up from AAP's Model Town office, is on his way to the Parliament Street police station.
AAP leader and former Delhi Law Minister Somnath Bharti has also reached the police station.
An FIR was lodged last night at Parliament Street Police station against Ilmi and Ashutosh and other AAP volunteers in connection with clashes outside BJP headquarters here.
Police had initially detained 33 people out of which 14 were arrested late last night while others were allowed to go.
A local court granted bail to those 14 AAP volunteers this afternoon.
"All those identifiable and present at the protest site have been named in the FIR," a senior Delhi Police official said.
Around 28 people, including 13 AAP activists and 10 BJP supporters, were injured in the clashes, police said.
Police have termed the AAP protest as completely illegal as no prior permission was sought by the party. Police said they have got the entire sequence of events videographed. Senior officials said more arrests are likely in the case.

AAP accuses Delhi Police of bias

Ilmi accused the Delhi Police of targeting the AAP and wondered why no action was being taken against BJP activists.
"On Wednesday, we got to see the discrimination of Delhi Police, which joined BJP to disperse AAP supporters staging silent protest. Police could not see bricks, stones and chairs being thrown from the inside of BJP Headquarter... They could only see people much later retaliating. Police were protecting BJP supporters," Ilmi claimed.

Ashutosh also accused Delhi Police of bias against AAP workers.

"AAP supporters were injured in the clash. BJP leaders beat up our supporters. Delhi Police takes action when flower pots at BJP office were damaged but they didn't take action when our supporters were injured," he claimed.
Election Commission slaps notice on AAP
A notice was on Thursday slapped on the Aam Aadmi Party by election authorities for alleged violation of the Model Code of Conduct over Wednesday's violent protest by Kejriwal party supporters outside BJP headquarters in the national capital.
The AAP has been asked by New Delhi's Deputy Commissioner and District Election Officer to explain by 3 pm on Thursday as to why action should not be initiated against it for holding a protest without permission from poll officials and in violation of the Model Code.
"The Model Code of Conduct came into force on Wednesday and permission has to be sought from the competent authority for holding any kind of gathering or procession which is related to election issue," New Delhi's DEO Ameya Abhyankar said.
Once the Model Code comes into force, all political parties have to seek prior permission from poll authorities before carrying out any activity which is related to polls.

The notice to AAP comes in the wake of a BJP delegation meeting the Chief Election Commissioner and seeking strict action against AAP and its leaders for violent incidents outside the BJP headquarters.

BJP approaches EC, demands strict action against AAP

Accusing Aam Aadmi Party of spreading anarchy and vitiating the atmosphere ahead of polls, BJP approached the Election Commission and demanded strict action against it, including the party's de-recognition.
BJP also alleged that some foreign forces were behind such violent incidents to create instability in the country and demanded a probe.
A delegation of BJP leaders including party Vice President Mukhtar Abbas Naqvi, Shyam Jaju and Delhi unit chief Harshvardhan met Chief Election Commissioner V S Sampath and ECs H S Brahma and S N A Zaidi and handed over a memorandum to them against AAP.
The BJP delegation also handed over a CD of Wednesday’s violent incidents outside the BJP headquarters here and demanded a probe and action against those working at the behest of "some foreign forces" that threaten democratic system in the country.
Kejriwal apologizes for party workers' behaviour

Meanwhile, Kejriwal apologized for his party workers' behaviour in Delhi and Lucknow while protesting his "detention" and urged them to stick to non-violence.
"It was going to happen...some of them retaliated after they were attacked...I apologize for their behaviour and I once again urge them to remain non-violent," he told reporters here in response to a query on the arrest of over a dozen AAP workers in Delhi.
AAP workers had on Wednesday clashed with BJP counterparts outside saffron party headquarters in Delhi and Lucknow after Kejriwal's car was damaged in Gujarat in retaliation to protest against his brief "detention" in the state.
