Cllr Darren Sanders, Cabinet Member for Housing, said: "This was a terribly shocking incident for residents, our police colleagues and our staff. Our thoughts are especially with the officer who was hurt, of course, and his loved ones. We are particularly proud of our staff, who responded superbly.
"We would like to reassure residents that we and Hampshire Constabulary work very hard on protecting our community from crime. Incidents like this are not common in Portsmouth.
"Three temporary CCTV cameras were set up last year at this location after reports of drug activity. The issue died down and the cameras were moved to another area where they were needed. After discussions with police, we will now install CCTV permanently, to reassure local people, and have reopened the adventure playground."
