Amandeep Singh, 23, a resident of Tagore Garden in west Delhi was arrested on Friday along with his associate Jitender, 22, a resident of Shahdara in east Delhi, police said on Saturday.
Fluent in English, he posed as a junior resident in the Safdarjung Hospital and the All India Institute of Medical Sciences (AIIMS), stole mobiles and handed them over to Jitender who sold them.
Amandeep was finally caught when a senior doctor at Safdarjung hospital, suspecting him of the thefts, checked his records and informed the police.
"Amandeep had big dreams and wanted to become a doctor to lead a lavish life. But his family couldn't afford his education and he dropped his studies after class 12," said a police official.
Hunting for a job, he reached Safdarjung hospital and instead decided to steal the mobile phones and valuables of doctors by posing as a doctor himself.
He then stole a coat and stethoscope and started roaming the corridors of the two hospital hunting for valuables.
