The security agencies were sent into a tizzy after Rakesh Kumar Verma's family lodged a complaint with the police on September 3, they added.
He is posted as a constable with the SPG.
Mr Verma had left home for work on September 1 but did not return home on September 2. He was off duty on September 1 but had still left home for work. He met some colleagues and was later dropped at Udyog Bhawan Metro Station, the police said.
He decided to leave his family and kept on roaming in parks in New Delhi area. Today, Mr Verma was found by a man who saw him in a pitiable condition asking for food and water near Tilak Marg. The man saw an SPG ID card with Verma and informed the SPG control room. The police were subsequently informed.
Mr Verma was medically examined and handed over to his family, they added.
