OKLAHOMA CITY - In a disturbing case, Oklahoma City police say a man is being held on a terrorism charge after allegedly threatening to behead a female coworker.

According to Capt. Dexter Nelson, with the Oklahoma City Police Department, a woman working at the Bellevue Nursing Home filed a police report on Sept. 16, claiming a co-worker made a comment to her that made her worried.

The alleged victim claims 30-year-old Jacob Muriithi started speaking with her after noticing that she was wearing a Star of David necklace.

The police report claims that Muriithi told the victim that he "represented ISIS."

When asked what that meant, the arrest affidavit claims that Muriithi told her "they kill Christians by cutting off their heads."

According to a report by an Oklahoma City police detective, the alleged victim asked Muriithi why, to which he replied "that is just what we do."

"The suspect did make reference to ISIS, and an affiliation with them," said Nelson.

The alleged victim claims Muriithi then asked her what time she got off work.

The report claims the suspect "told her he was going to wait until she got off work and cut her head off."

The victim says she thought he was joking because he has a dry sense of humor.

She asked if he had a guillotine set up outside, but he said he "was going to cut her head off with a dull blade, then post it on Facebook."

At that point, she says he appeared to be serious and did not seem like he was joking.

Co-workers overheard the conversation and called the FBI.

When questioned by police, Muriithi allegedly said he was only joking.

"You don't actually have to carry out a threat. It's still a crime if the victim believes the threat to be credible," said Capt. Nelson.

"I'm shocked about the whole thing really," said neighbor Fred Mumford.

"It's just kind of shocking," said neighbor Charles Clark.

Both Clark and Mumford have lived next to the suspect's home for years.

They both hope the suspect wasn't serious about killing his coworker.

"I hope it's a joke," said Clark.

"I'm hoping it's a misunderstanding because he seems like a nice guy," said Mumford.

Those two neighbors admit ISIS, a terrorist group known for violently beheading Western hostages, is not a laughing matter.

"You just don't want to joke about that. It's too serious of a subject," said Clark.

Managers at the nursing home fired the suspect just a few days after the threat was made.

They say they did a background check on him, which revealed no criminal record.

Muriithi had been arrested and charged with one count of threatening an act of violence.

In light of recent events, the district attorney has upgraded the charge to making a terroristic threat.

The alleged threat occurred nearly two weeks before the violent beheading at Vaughan Foods in Moore, but it was only after that crime that police arrested the suspect in this case.

Court records claim the suspect admitted to making the threat, but denied being a member of ISIS or even being Muslim.

Muriithi, who is from Kenya, asked police if he would still be allowed to travel back to Kenya with his family.

Since prosecutors fear he would be a flight risk, Muriithi is being held on a $1 million bond at the Oklahoma County Jail.
