The three youngsters, including two girls, who were arrested for criminal trespass at the high-security official residence of the Prime Minister, were granted bail on Friday.
After being booked under charges of criminal trespass and impersonation, the trio -- Yogita, Bina and Imran -- were granted bail on a personal bond of Rs 25,000 each and a surety of like amount.
"We had received a call about intrusion into the Prime Minister's residence on Friday night after which we detained and interrogated three youngsters. Subsequently, we arrested them earlier in the day for using another name to gain entry into the high-security residence," DCP (New Delhi) Anand Mohan said in New Delhi.
All the accused were released on bail and investigation into the case was on, he said.
In a breach of security, the trio, in a black luxury car, drew up to the first inner gate near the alighting point at the Prime Minister's Seven, Race Course Residence, after passing through a security cordon at the main gate just before 9:00 pm on Thursday night.
Mohan said the vehicle was owned by Yogita, who purchased it three months back.
