Two policemen danced and hugged with several women at a swingers party just hours before members of the Critical Incident Response Team stormed Inflation nightclub and shot a couple last month.

CCTV footage obtained by Fairfax Media shows the male officers appearing to enjoy the attention of at least four women dressed provocatively at the Saints and Sinners Ball on July 8.

At one point a woman "twerks" against a policeman, while his colleague embraces another female patron for more than a minute. Both men are armed and in police uniform.

The two officers make no attempt to rebuff the women during the 10-minute interlude near the club's dance floor.
