Health authorities are investigating a chiropractor after a “disturbing” video emerged of him performing spinal adjustments on a two-week-old baby.

Footage uploaded to social media shows Mr Andrew Arnold, owner of Cranbourne Family Chiropractic in Melbourne, dangling the infant boy upside-down by his legs before using a spring-loaded ‘activator’ on his spine and neck.

Victorian health minister Jenny Mikakos condemned the video and referred Mr Arnold to AHPRA and the Chiropractic Board of Australia for investigation.

“The video image of a two-week-old infant being held upside down while crying hysterically and having both their neck and their spine manipulated was extremely disturbing to me,” Ms Mikakos said.
