Ramdev's chief spokesman S K Tijarawala alleged that Tyagi, who worked as a driver with Patanjali yogpeeth, had stolen machine parts worth Rs 25 lakh and other valuables about two years back.
He entered Patanjali Yogpeeth premises yesterday and was found under suspicious circumstances.
Tijarawal claimed Patanjali yogpeeth employees overpowered him and reported the matter to the police but no one arrived.
“When no one came and we were going to hand him over to the police, we were intercepted by police personnel on the way. Tyagi was taken into custody and instead of acting against him, a case of abduction was lodged against us,” Tijarawala alleged.
