Former NFL wide receiver Keyshawn Johnson reportedly chased Justin Bieber back to his home after he allegedly saw the singer racing a white Ferrari around the gated Calabasas, Los Angeles community where they both live.

However, vastly conflicting accounts have emerged over who was driving the vehicle. An unnamed source told Radar Online that the rapper-producer Tyler, The Creator — full name, Tyler Gregory Okonma — was driving the Ferrari and not Bieber.

TMZ maintain that Johnson “clearly saw” Bieber behind the wheel. The website also claims law enforcement officials have said “multiple witnesses” report the same.

Johnson’s agent, Jerome Stanley, reportedly told TMZ his client was: “Very, very livid,” and that, “Keyshawn is taking the situation very seriously.”

The agent added: “He wants Justin to slow down and be a responsible neighbor.

When asked if Johnson would continue to help police with their investigation, Stanley replied:

“Keyshawn is a law-abiding citizen and he’ll do whatever it takes to help the authorities.”

At about 8 pm Monday, Bieber allegedly drove his white Ferrari at freeway speeds in what is a 25 mph zone, Sheriff’s spokesman Steve Whitmore said.

Whitmore said police received two separate calls from two witnesses claiming the Canadian singer was driving at high speeds.

Johnson says he was outside with his three-year-old daughter when Bieber is alleged to have sped past. The 40-year-old reportedly immediately got into his Prius and tailed the teen star to his property to confront him.

On arriving at Bieber’s home, Johnson told police he put his arm out to stop the garage door from closing while telling the 19-year-old he wanted to talk to him.

The singer reportedly quickly went inside his house without speaking to the ex-NFL star. Deputies who attended at the star’s home were similarly turned away at the door.

Whitmore said: “His security detail said he [Bieber] declined to talk to us based on the advice of counsel.”

Police officers at the scene spoke to two witnesses, including Johnson, before filing a report with investigating detectives. Of the witnesses, Whitmore said:

“Their eyewitness testimony to our deputies was definitive — not only the speed, not only the vehicle, but Bieber was sitting and driving in the driver’s side seat.”

Another former NFL legend Eric Dickerson, who also lives in Calabasas, offered his opinion, tweeting:

Hey @justinbieber I use to have a white Ferrari too, but I knew the speed limit in neighborhoods where kids played. twitter.com/EricDickerson/… — Eric Dickerson (@EricDickerson) May 28, 2013

Sheriff’s deputies intend to present a reckless driving report to the L.A. County District Attorney’s Office to consider filing misdemeanor charges within the next two weeks.

Prosecutors are also mulling whether to charge Bieber for battery in a separate incident after another Calabasas neighbor claimed the teen heartthrob spat and threatened him.

“We take this very seriously and if this actually did occur, which it appears that it did, it is unacceptable behavior from anybody, anywhere, anytime,” Whitmore said of the reckless driving allegations.

TMZ is reporting that sources close to Bieber’s team have told the D.A.’s office that they have a witness prepared to swear on oath that the singer did not spit on the neighbor.

Meanwhile Bieber, who is currently on a break before the North American leg of his Believe tour resumes from June 22, attended an ice hockey game with a few friends at L.A.’s Staples Center on Tuesday.
