George Ssenkaa levelled matters for Express with a header from the corner kick in added time of the first period.
Youngster Ivan Mayanja netted the second for the Red Eagles in the 56th minute.
It was a game of two halves at the Muteesa II Stadium with the Cops dominating the first period but the hosts had an improved second half.
Mawejje who had given the Cops an early lead was again denied by Express goalie Otim.
Enock Ssebaggala nearly levelled matters for Express but his effort hit the crossbar in the first period.
Eric Kambale also had a golden opportunity to strike for the hosts but was denied by Police goalkeeper Tom Ikara who replaced injured Abdul Kimera in goal.
Express who had a changed second half could have scored more but both Mayanja and Kambale were culprits for missing several opportunities.
