The twowoundedpolice officersandthecivilian - who was shot as he wrestled with Molenaar during Thursday's melee - remained in critical condition in a hospital.
Deane limped off through injury at half-time, but Dickov swept home a 67th minute penalty past Aidan Davison after being hauled back in the box by Robert Molenaar.
Molenaar, twice named in the National One team of the year, has been with the Green and Whites for five years and believes the club has a bright future.
