The BBC has obtained footage of the moment a man arrested by a Wiltshire PC was tasered inside a police cell in Melksham in 2012.
PC Lee Birch, who fired the stun gun, was cleared of assault on Tuesday 29 April after a jury saw the footage.
The Independent Police Complaints Commission (IPCC) has begun an investigation into whether PC Birch breached standards of professional behaviour.
