The National Investigation Agency probing the Mansukh Hiran murder case has recorded the statement of a hawker who has been selling handkerchiefs outside Kalwa railway station.
The agency suspects arrested cop Sachin Waze bought a few hankies from this vendor before meeting Hiran on March 4.
Sources in the NIA said CCTV footage from the location shows a person with a similar appearance as Waze buys many handkerchiefs from the hawker.
Waze is accused of getting Hiran, a car decor dealer from Thane, killed.
Hiran’s SUV was found loaded with explosives near Mukesh Ambani’s home Antilia on February 25.
When Hiran’s body was found in a creek near Mumbra, it had a monkey cap and handkerchiefs in his mouth.
NIA suspects the pieces of cloth were purchased from the Kalwa hawker.
The NIA is painstakingly piecing together direct and circumstantial evidence to make a watertight case against Waze and the other accused, said sources.
