Action star Alan Ritchson was caught on camera allegedly attacking his Tennessee neighbor during an explosive street brawl on Sunday.

The Reacher actor, 43, appeared to throw multiple punches at the alleged victim in front of two children on motorbikes – believed to be his sons – in a video obtained by TMZ.

In the clip, the 6ft3in leading man – who has previously spoken about being diagnosed with bipolar disorder – is seen striking a man on the ground several times.

Ronnie Taylor, the alleged victim, told the publication that the incident started on Saturday when Ritchson was riding his green Kawasaki bike through their quiet upscale neighborhood.

Taylor alleged that the entertainer was going at an excessive speed, as well as revving his engine and disturbing the peace.

A Brentwood Tennessee Police Department spokesman told the Daily Mail: ‘There is an active investigation, and no arrests have been made. There will be a police report available when the investigation has concluded.’

The Daily Mail has also reached out to Ritchson’s representative for comment and has yet to hear back.

The neighbor says he flipped Ritchson off, and the actor responded in kind.

The following day, Ritchson rode through the neighborhood again at around noon – this time with two kids on their own bikes – and was allegedly speeding.

Taylor asked Ritchson, ‘Can you f*****g stop this please,’ which is when the situation escalated.

The alleged victim claimed he reported that Ritchson punched him in the face and kicked him to the police.

He also claimed that the actor proceeded to fall off his bike, before getting up and attempting to run him off.

Taylor also alleged that Ritchson hit him ‘at least four times’ and in the back of the head at one point.

He said the incident, which was reportedly witnessed by neighbors, left him with bruises and swelling, but he did not go to the hospital.

Law enforcement sources confirmed to TMZ that an investigation is underway into an incident, though no arrests have been made.

In the clip, Ritchson is seen picking up his helmet off the ground and grabbing his bike after allegedly assaulting Taylor.

He then loses control of the bike, which veers onto the lawn. Meanwhile Taylor is seen picking something off the ground and walking up to Ritchson, and then away again. The actor then gets back on his bike and drives off, followed by the two youngsters.

‘I was diagnosed as bipolar right after. Deep down, I was comforted to know, “OK, there’s a name for this.”‘

A friend then suggested he try MDMA therapy with his wife Catherine.

‘I swear to God, the biggest light bulb went off, and it rewired my brain in the best way. MDMA is a proven therapy to treat PTSD in veterans, and it’s something that can work in cognitive therapy settings.’

The therapy session made him reflect on his existential journey and conclude that his purpose is ‘to make the world a better place and serve others.’

Ritchson’s epiphany prompted him to seek out more fulfilling opportunities in his career, ultimately leading him to the TV series Reacher.

During his interview, Ritchson also claimed he had been sexually assaulted while working in the modeling industry.
