據報道，6月4日在切爾西橋路，41歲的Oladeji Adeyemi Omishore拿着一把螺絲刀，警察正試圖將他拘留。
A man who died after being Tasered on a west London bridge and then pulled from the River Thames was not armed with a screwdriver but was holding a firelighter, the police watchdog said.
Officers were trying to detain Oladeji Adeyemi Omishore, 41, after reports he was armed with a screwdriver on Chelsea Bridge Road on 4 June.
Investigators said the interaction between two Met Police officers and Mr Omishore was being looked into and appealed for witnesses.
The IOPC has now confirmed Mr Omishore was holding a plastic and metal firelighter when he was approached by the officers.
A Taser was discharged by one of the officers prior to the man entering the river, the IOPC added, and was discharged "more than once".
A post-mortem examination has taken place and the IOPC said it was awaiting the results. An Inquest into Mr Omishore's death was also opened and adjourned on 15 June.
IOPC's Sal Naseem said: "Our thoughts remain with Mr Omishore's family and all of those affected by his death.
"Our investigators continue to gather and analyse key evidence, including footage recorded at the scene and initial accounts from officers and members of the public.
"We would urge anyone else who may have witnessed or recorded any part of the incident, either on the bridge or after Mr Omishore entered the river, to get in touch with us without delay. It is important we understand all of the circumstances surrounding his death."
