The 10 Additional Metropolitan Magistrate court on Friday extended Judicial custody of Buela Sam to 25 of this month.
Ms. Sam was caught for intruding into ISRO campus on fake ID card posing as environmental scientist, hoodwinking the CISF security.
The JB Nagar police who initially suspected Ms. Sam was suffering from mental disorder, questioned several persons to corroborate her statement.
While the JB Nagar police are corroborating the statements of the suspects in the case, Buela is being constantly monitored by a team of doctors from Nimhans to ascertain her mental condition.
So far it has been ruled out about her possible link to terror outfits, but the investigations are on to probe various other missing links, a police officer said.
