National Super League (NSL) side Nairobi City Stars opened a seven-point gap on top of the table after defeating Kenya Police 2-1 on Saturday.
The former Kenyan Premier League (KPL) side had won the first leg 3-2 and were keen on completing a double against the administrative side.
The Simba wa Nairobi custodian committed a foul in the 18-yar area after just seven minutes and the referee awarded Police a penalty. Skipper David Oluoch converted from 12-yards to give the Charles Omondi-led side a lead.
The hosts went into the half-time break on level terms after the Police goalkeeper brought down former AFC Leopards midfielder Peter Opiyo, conceding a penalty in the process.
