The teenager was caught weeks after he opened his own medical office

A Florida teenager was arrested for pretending to be a doctor after giving an undercover police officer a medical exam at an illegal practice he opened - a year after he was caught posing as a gynecologist.

Malachi Love-Robinson, 18, was released from the Palm Beach County jail on Wednesday on $21,000 bond on charges of practicing medicine without a license, fraud and grand theft.

Palm Beach County sheriff's spokeswoman Teri Barbera said Love-Robinson was arrested on Tuesday after he performed an exam on an undercover agent and gave medical advice.

Love-Robinson claimed to be 25 and the co-founder, president and CEO of New Birth New Life Holistic and Alternative Medical Center & Urgent Care center in West Palm Beach, where he masqueraded as 'Dr Malachi A Love-Robinson, PHD, HHP-C, AMP-C'.

But his police said his medical 'career' ended abruptly when the fake doctor was caught in the act.

The Department of Health served a notice to cease and desist and issued Love-Robinson several citations, authorities said.

Love-Robinson's grandfather, William Robinson, told the Sun Sentinel that his grandson never claimed to be a medical doctor, only a 'holistic doctor.' He said his grandson had never seen patients.

But the latest incident is the third time in just over a year that Love-Robinson has allegedly been found to be pretending to be someone he is not.

After his latest arrest, he told WBPF: 'All these are accusations and I will have my lawyer contact you.'

In January 2015, he reportedly impersonated a gynecologist at St. Mary's Medical Center and looked in on exams.

Dr. Sebastian Kent, an OB/GYN at the center, told the Sun Sentinel: 'I've been in practice for 36 years, this is the first time something like this has happened. It's very strange. Very, very strange.

He was caught in a pregnant woman's exam room in St. Mary's Medical Center wearing a coat, a face mask and stethoscope with the clinic's logo, WPBF reported.

But the station also reported that staff had seen the teenager roaming the halls for around a month before that incident.

But the center denied the then-17-year-old Love-Robinson had ever come in contact with patients and decided against pressing charges.

Afterwards, Love-Robinson denied he had pretended to be a doctor, telling the station: 'I requested to shadow some physicians. The next things I know, the cops are there.'

Love-Robinson's biography on the New Birth New Life website refers to him as a 'well rounded professional' and highlights his preference for alternative therapies

Then, he was investigated and cited by the Department of Health for practicing medicine without a license in October 2015 after allegedly posing as a massage therapist without a license at a rehab center in Boynton Beach.

But in January this year, the Sheriff's Office as well as the Palm Beach Narcotics Task Force (PBNTF) and its partners at the Florida Department of Health began investigating Love-Robinson again after receiving an anonymous tip.

Three weeks ago, the teenager had thrown a grand opening for his clinic, leading concerned family members to report him to authorities, according to WBPF.

'Our investigation revealed that Love-Robinson had opened a medical office at 4700 north Congress Avenue, suite 303, West Palm Beach, Florida and was presenting himself as a medical certified doctor,' a spokesman for the Sheriff's Department said.

'Members of PBNTF and Department of Health conducted an undercover operation at the medical office of Love-Robinson. During this undercover operation, Love-Robinson performed a physical exam on an undercover agent and offered medical advice.'

Meanwhile, Love-Robinson's profile on New Birth New Life's website shows him with a white lab coat and stethoscope.

It describes him as 'a well rounded professional that treats, and cares for patients, using a system of practice that bases treatment of physiological functions and abnormal conditions on natural laws governing the human body'.

It goes on to say that he 'utilizes physiological, psychological, and mechanical methods'. These methods apparently include 'air, water, light, heat, earth'.

On HealthGrades, a site that lets users rate doctors, Love-Robinson's profile includes a personal statement that reads 'I believe that if you restore your health the natural way and the right way you will be able to maintain that grade of health easier and more efficiently, why? because is natural [sic].'

It also states his age as 25.

The case has drawn comparisons with fictional TV doctor Doogie Howser - played by Neil Patrick Harris - who was a physician from the age of 15 in the hit 1990s comedy series.
