The police in Bengaluru have discovered at least two instances of criminals using SIM cards — obtained through the Aadhaar authentication of someone else — to avoid being tracked down by the officers hunting for them. In both cases, the police said, the dealers kept the Aadhaar details of those applying for a SIM and issuing SIM cards to some unknown people. Some network operators offer up to 10 SIM cards to a person after identifying his or her Aadhaar details. Police said that the dealers used this policy to obtain the SIM cards fraudulently.
