Darbhanga Senior Superintendent of Police Babu Ram said, "Six of the minor girls were found in Gangauli village under the Sakatpur police station area late in the evening".
He said a police team had come from Patna district in search of the missing girls based on the inputs they had gathered during investigation. One of the girls belonged to Gangauli village.
The girl, along with five others, was found at the village and the visiting police team has taken them into custody for interrogation, the SSP said.
Opposition parties flayed the NDA government in Bihar, alleging that five of the girls were "witnesses" in the sex scandal being probed by the CBI under the supervision of the Supreme
Court, and claimed their escape was a "conspiracy" hatched by the ruling dispensation to protect "big shots".
"Seven girls have escaped from the shelter home. They are said to have fled after cutting the grill of a window at about 3 am. They were under treatment for their violent behaviour," Social Welfare Department Director Raj Kumar told PTI.
It is yet to be ascertained whether the girls include former inmates of the Muzaffarpur Balika Grih, he said.
Hours later, Deputy Inspector General (Patna Range) Rajesh Kumar reached the spot for inspection and said, "We are conducting investigations taking all possible angles into account."
Sniffer dogs and forensic experts were pressed into service to trace the girls who had fled the home situated around 100 km from the state capital.
Meanwhile, Leader of the Opposition in state Assembly Tejashwi Yadav tweeted: "Five witnesses of the Muzaffarpur rape case have been made to disappear from Mokama shelter home to protect the chief minister and the government machinery."
Yadav's mother Rabri Devi, who is leader of the opposition in the Legislative Council, said, "Chief Minister Nitish Kumar should tell us why he is so scared."
The girls went missing a few hours before hearing in the Muzaffarpur case commenced at a Delhi court, where trial was transferred from the north Bihar town following a Supreme Court order earlier this month.
RLSP chief Upendra Kushwaha slammed the Nitish Kumar government over the incident.
"It appears that the girls have not flee of their own accord, but their escape has been facilitated by the government since the Supreme Court and the CBI have questioned the role of the chief minister in the scandal. Nitish Kumar should resign as other surviving victims face threat to their lives from him," Kushwaha said in a tweet.
Congress MLC Prem Chandra Mishra said, "It appears that attempts are being made to save some people in the Muzaffarpur case. The Supreme Court should take note of the disappearance of girls from Mokama."
Hindustani Awam Morcha president Jitan Ram Manjhi issued a statement from Ranchi, alleging that the chief minister and Bihar DGP Gupteshwar Pandey be held accountable for the disappearance of the seven girls "which has been made possible to affect the probe into Muzaffarpur sex scandal".
The scandal had come to light in May last year after an FIR was lodged by the Social Welfare Department based on the social audit report of Mumbai-based Tata Institute of Social Sciences.
More than 30 girls were lodged at the shelter home when the scandal came to light and medical examinations confirmed that most of them had been subjected to sexual abuse. The shelter home was subsequently sealed and its inmates were moved to care units in Madhubani, Patna and Mokama.
The case was later handed over to the CBI on the recommendation of the state government which, thereafter, also decided to give up the practice of awarding contracts for running shelter homes to state-funded NGOs.
The girls escaped in the early hours of Saturday after cutting through a window grill. Five of them were victims of the Muzaffarpur shelter home scandal.
