The teen arrested in West Palm Beach Tuesday for practicing medicine without a license also faces grand theft charges, according to the Palm Beach County Sheriff's Office.

Officials say a complaint prompted the Palm Beach Narcotics Task Force (PBNTF) and the Florida Department of Health to start an investigation on the suspect, 18-year-old Malachi Love-Robinson.

Love-Robinson was investigated and cited by the Department of Health for practicing medicine without a license in October 2015.

PBSO's investigation revealed that Love-Robinson had opened a medical office at 4700 North Congress Ave., Suite 303 in West Palm Beach and was presenting himself as a medical doctor.

"I've heard of these things happening, but you’re right, I never thought it would happen in this building," said Dr. Allen Schultz, an oncologist on the same floor of the professional medical building.

Dr. Schultz says Suite 303 was empty until a few weeks ago.

"All of a sudden I saw the name on the door there. I never saw the person. I never saw anybody even working in there," added Dr. Schultz.

Even the directory board at the medical building says Dr. Love-Robinson has a PhD and other certifications. Investigators with the Palm Beach County Sheriff's Office say Love-Robinson is accused of performing a physical on an undercover agent and offered medical advice.

In addition, an 86-year-old woman claims Love-Robinson defrauded her after a series of visits to her home to treat her for severe stomach pain. She said he diagnosed her with arthritis and sold her natural vitamins. But during one visit she became so sick she called an ambulance. Before going to the hospital the woman claims Love-Robinson recommended that she leave her purse and keys at home. She said that she gave them to him and asked him to lock up her house.

Later the victim learned her bank account was empty so she obtained copies of three checks that she said Love-Robinson forged and cashed without her consent. They totaled $2,794. She said that was in addition to the $3,494 she paid him for the doctor visits and vitamins.

Bank of America produced images showing Love-Robinson negotiating the checks, according to a probable cause affidavit. The sheriff's office has charged him with grand theft and uttering a forgery.

"He made these house calls which I thought were a little strange," Anita Morrison in a phone interview.

Morrison says she was vulnerable when she found Dr. Love-Robinson.

"I had severe pain and I would call him and hell say I'll be right over, I have just the right pill for you for the pain," said Morrison. "When he came along I said good, I said God is good, he sent him he's going to help me and this is what turned out."

Love-Robinson wouldn't address the accusations made by the elderly woman. His grandfather William McKenzie is still in disbelief.

"Well once he opened up the office and the practice I felt like it was something legit that he’s trying to do," said McKenzie.

To an outsider the alleged practice would appear legit. According to HealthGrades.com, a site where patients can find local doctors, Love-Robinson's profile says he specializes in naturopathy, psychology, and mental health. It also says he's 25-years-old.

"If he has slipped and did something wrong I just ask everybody to pray for him," added McKenzie.

Love-Robinson was served a notice to cease and desist and several other citations by the Department of Health.

He has since bonded out of jail.

Love-Robinson represented himself to be a doctor through a Facebook page (pictured below) and through a website, nbnlmedicalcenter.com.
