They also thanked Firoze, the person who took the video clip.
Gambhir was received by Lok Sabha MP, Dr. Th. Meinya and Local MLA of Konthoujam, Dr. Sapam Ranjan Singh.
Back in 1978, Gambhir, 26, had left his home for reasons unknown and later went missing.
The family was unaware of Singh's whereabouts for 40 long years until their nephew, Romen Leichombam, brought a video of a grey-haired and bearded man singing old songs to their notice. The video was shot and uploaded on video-sharing website YouTube last October by a Mumbai-based photographer Firoze Shakir who saw Gambhir singing on Mumbai streets.
In the clip, the singer identified himself as Khomdan Singh of Manipur, which caught the nephew's attention. The video further caught the attention of Aheibam Dinamani, an assistant professor at NERIST university of Arunachal Pradesh, who contacted Romen and informed him about the man living on the Mumbai streets.
Unable to get Gambhir back on their own due to their financial conditions, family contacted Mumbai Police and lodged a complaint with Patsoi police station.
Earlier, activist Angellica Aribam had sent out a request to Mumbai Police to trace the missing man. (ANI)
