A 26-year-old employee of a Mulund-based accounting firm, S Wadekar, has been arrested for staging his own robbery in connivance with a friend. The latter, Chetan, ‘robbed’ Wadekar of over Rs 13 lakh in cash after sedating him with chloroform. The accused had almost succeeded but were captured signalling each other with their hands shortly before the incident by a CCTV camera.
