Police Commissioner Owen Ellington says the men and women under his command will not cower in fear, despite criminals carrying out deadly attacks on police personnel.
Ellington's comments follows Friday night's fatal shooting of 23-year-old Special Constable Arianna Henry.
The special constable died at hospital after she was shot near her home in Marine Park, Portmore, St Catherine.
Henry's death brings to seven, the number of police officers murdered since the start of the year.
The commissioner said he has instructed investigators assigned to the St Catherine South Police Division to move apace in capturing the remaining criminals involved in the murder of Henry.
Reports from the Portmore Police are that about 8:45 p.m., Henry, who was attached to the National Intelligence Bureau, was in the company of another police officer, when a Toyota Corolla motor car with armed men aboard drove up and ordered them not to move.
The police further reported that four men alighted from the vehicle and opened fire at the officers hitting Henry in the abdomen.
Meanwhile, the police are reporting that the officer who was with Henry at the time of the incident shot and injured one of the gunmen.
A man, who the police said was one of the gunmen involved in the shooting, turned up at the Spanish Town hospital for treatment, and was placed under police guard.
The police said they recovered a Bryco Arms 9 mm pistol along with a magazine containing nine 9mm rounds of ammunition from the scene of the shooting.
Peter Bunting, the minister of national security, yesterday expressed outrage at the killing of Henry.
"It is a particularly shameful and reprehensible act to ruthlessly murder a young woman in the dawn of her service to country," Bunting said.
The national security minister charged that there are criminals in communities "who are intent on wreaking havoc and disrupting peace and order in our society".
"They must find no safe haven amongst us," Bunting said.
