John Goddard, 49, also presented himself as a terrorist and said the loyalist paramilitaries were about to end their ceasefire in order to “annihilate” the PSNI.
The bogus phone threats were part of a year-long catalog of offenses that his lawyer called inexcusable.
Goddard, of The Mount, pleaded guilty to persistent misuse of a communications network to cause anxiety, assaults on police and disorderly behavior.
He also admitted to begging and breaking an antisocial behavior ordinance.
Belfast Magistrates’ Court heard he contacted police 13 times in an hour on July 8, 2020.
Iryna Kennedy, prosecuting, said Goddard pretended to be a terrorist during a series of threats.
“He said that the loyalist paramilitaries would break their ceasefire and wipe out the PSNI,” the lawyer revealed.
“He then made further calls, stating that he had planted various car bombs at specific locations in Belfast and was going to kill Catholics.”
Police then located Goddard and seized a phone used in the fake messages.
In a separate incident on September 28 last year, the defendant ignored warnings about his behavior on Great Victoria Street in the city and called the police ‘black b******s’ and “Fenian b******”. s”.
During attempts to restrain him, Goddard bit a police officer on the fingers and threatened to bite his nose, the court heard.
Other charges involved spitting in the face of a police officer, getting into a fight outside a downtown bar, being unruly and drunk in a supermarket.
The defendant had also shouted at a member of the public “I’m going to f****** stab you to death”.
Defense attorney Michael Boyd acknowledged: “It’s a catalog of serious offenses and difficult to find an excuse to explain his behavior.”
However, he described Goddard as a vulnerable person who had been “damaged” by years of alcohol abuse and homelessness.
“He kind of became an amusing figure among the other people in that locality,” Mr. Boyd said.
Imposing a total of six months in police custody, District Judge Mark McGarrity admitted Goddard to his guilty pleas.
The judge added: “Unfortunately he is not fit for probation or community service.
