Chicago police superintendent David Brown told reporters on Monday that the number of attacks on police officers is "five times" greater than in previous year.
Brown said that of the 65 Chicago police officers that have been shot at, 10 were struck.
"There is not a comparable year," Brown said. "That is five times any previous year that anyone can recall in this city."
The shootings include several high-profile incidents, such as the two officers who were wounded in August after being shot during a traffic stop and another officer who was shot in the leg while arresting a suspect in August.
Another three officers were shot in August when an arrested suspect produced a gun and engaged in a shootout with the officers. One officer shot in the attack had to be placed in a medically induced coma.
