Agyemang makes Portsmouth exit
The experienced 34-year-old scored eight times in 69 appearances for Pompey since arriving from Stevenage in January 2013.
Agyemang spent a four-game loan spell with Dagenham earlier this season but failed to find the back of the net.
A club statement read: “Portsmouth Football Club would like to thank Patrick for his efforts while at Fratton Park and wish him well for the future.”
