A Fredericton man was fined and placed on probation Monday for assaulting and threatening a park/trail patrol official last week.

Rizzieri Antonio Lozano, 18, of 8 Little Lane, pleaded guilty Monday to July 20 charges of uttering threats and assault, as well as a Feb. 13 charge of theft and a May 10 charge of failing to appear in court.

He was brought to court Monday in custody. He had been held in custody since his arrest last week as there was an outstanding warrant for his failure to attend court in the spring.

Crown prosecutor Trent Wilson said park patrol constables encountered Lozano on a northside walking trail last Thursday afternoon and tried to stop him for failing to wear a helmet while riding his bicycle.

Lozano threatened to beat one of the officers and then upped his threat by suggesting he'd attack him with a weapon.

The accused said "Do you want to get stabbed?" to the patrolman, Wilson said.

Lozano first got in trouble in February when he tried to steal a $14.99 CD from CD Plus in the Regent Mall. Wilson said mall security officers had to corner Lozano to keep them there until police arrived.

The prosecutor said Lozano has no previous criminal record but was granted a conditional discharge for assaulting a police officer in 2004.

Wilson said it's clear Lozano has an anger-management problem.

"There appears to be some psychological issues at play," he said. "He's obviously got a problem with authority that needs to be addressed."

Duty counsel Doug Smith said he believes Lozano needs mental-health counselling.

"He's a loner," Smith said, and he believes Lozano will get into more trouble in the future if he doesn't get some help.

Judge Graydon Nicholas noted that the Crown did not ask for a jail sentence in the case, which was lucky for Lozano.

"In my mind, a jail term would be justified," he said.

Instead, he opted to impose a $287.50 fine and a nine-month term of probation.

Among the conditions of Lozano's probation are that he performs 30 hours of community service work and he undergoes assessments and counselling as recommended by his probation officer.
