Officers tackled the man to the floor after he rushed towards the coffin and tried to lift the Royal Standard, which was draped over the coffin of the late royal.
The shocking incident took place 10pm at Westminster Hall on Friday, when the man shoved mourners aside, including a seven-year-old girl, and rushed towards the coffin.
He was arrested on suspicion of a public order offence.
One witness told MailOnline: “We saw him (the man) in the queue from the beginning of the queue and throughout the day, he was by himself.
“When we entered the room we were at the top of the stairs when we saw the incident. A lady screamed as it happened it was quite unnerving. Although he was detained and people kept calm and carried on.”
“(It was) terrible, absolutely terrible, so disrespectful and unbelievable – and this poor little seven-year-old child, this is her lasting memory of the Queen.” – Bang Showbiz
