Shane Mayer died in hospital three days after he was stabbed outside Gabba’s Bar in Forge Road, Darlaston, on Wednesday July 24, 2019.
The 21 year-old, from Wolverhampton, had collapsed in a nearby street following the attack at just before 11.15pm.
Giving evidence at Birmingham Crown Court yesterday investigating officer Detective Constable Claire Ferguson reviewed CCTV footage.
Ramani Sanderson, who is accused of stabbing Mr Mayer in the leg allegedly with a knife measuring between 30 and 40 centimetres in length, is identified on the footage as Profile 1, co- defendant Kamron Reid is Profile 2 and Mr Mayer, Profile 7.
Addressing DC Ferguson about Profile 1, prosecutor Michael Burrows QC said: “You described him jumping around in the middle of the street swinging something around in the air.
“When is the first time you see a weapon?”
“On Forge Street,” replied DC Ferguson.
The officer said that outside Gabba’s Bar, Profile 1 appears to have his right hand behind his back holding a large straight item.
“Profile 2 appears to look down towards the item and back away from it,” she said.
“Profile 1 lunges out swinging it in the air.
“Profile 7 swings a punch - he is bending over, crouching. He looks down, holding his stomach.
“Profile 1 brings down the weapon onto the back of Profile 7.”
DC Ferguson said Profile 7 then runs to the end of Forge Road and is followed.
She told the court that that Profile 1 is then seen running along Forge Road towards Herberts Park Road with a long item held in the right hand which extends towards the ground.
“It gives you an idea of the size of the item,” said DC Ferguson. “It appears that long.”
Kamron Reid, 20, of Herberts Park Road, Bloxwich; Ramani Sanderson, 20, of Walsham Road, near Peckham, London; Joseph Till, 21, of Summer Street, Willenhall; and Lewis Green, 21, of Heathfield Lane West, Darlaston, all deny murder.
Sanderson also denies possessing a bladed article in a public place. Green has admitted carrying a hammer.
Sanderson is also standing trial accused of assaulting a taxi driver in a separate incident on April 29, 2019.
He is charged with wounding with intent, and possession of a bladed article in a public place. He denies both charges as well.
The trial continues.
