After relatives started to put the memorial back, a woman, who said she was Vincent's aunt, said: "If people leave the flowers alone within a week they'll die, we will come here, clean this road, and go and never come back".
Vincent died after being stabbed by 78-year-old Richard Osborn-Brooks in Hither Green on April 4 during a botched burglary, and a former associate of the criminal has issued the pensioner with a warning.
Mr Osborn-Brooks, who was arrested after Vincent's death but later released without charge, has been hailed a hero by some for taking on the burglar and his accomplice, who police are still trying to trace.
Video had earlier emerged online showing a man pulling floral tributes to Vincent down from fences.
The Met is keeping a "presence" in and around the Crescent to "provide reassurance to local residents", but a spokesperson said the location of the tributes is "not a matter for police". Officers want help from the public to find Billy Jeeves, 28, who is said to have links to Orpington and Swanley in Kent and Cambridge.
He said the tributes should have been left alone to "die off", adding: "I'm anxious these people might come back and cause a rumpus".
Floral tributes laid for a burglar killed last week in Hither Green have been pulled down once again. "[It was] inappropriate, and the guy deserves no tribute".
One tribute, thought to have been left by the dad-of-four's young daughter, said: 'Strangers can say what they like about you they don't no who you was so I don't care.
Theresa Webb, 43, a consultant nutritional therapist who lives on the road said the community are "mourning the loss of a life" but their first thoughts are with Richard and his wife.
Saverimuthu Augustine, 78, said some of the tributes had been attached to his property.
He said: "I don't appreciate it. There was 101 bouquets down there".
"If it's a normal person it's different, but he went and burgled a house - it could have been my house".
Several police vehicles were parked outside Mr Osborn-Brook's house on Tuesday, though the pensioner was not there.
The van was found burned out on the evening of Saturday 7 April in Star Lane, near Hockingdon Lane in Orpington.
During a struggle in the kitchen, Vincent was stabbed in the upper body. It is unclear what implement was used.
Both Vincent and Jeeves were already being sought for questioning by Kent Police following a series of burglaries in Farningham in January.
