(Inspired by true events)

Inspector Buddhi and her team were flummoxed. There had been a diamond heist at a huge jewellery expo in the city that morning and the Inspector was determined to catch the thieves. Unfortunately, the heist took place in a blind spot so there was no CCTV footage showing the crime. Inspector Buddhi was scanning the available footage of the expo for suspicious behaviour when she saw something that piqued her interest. Can you spot whom Inspector Buddhi pulled up for further questioning?
