Louis Dennis has joined League Two side Leyton Orient for an undisclosed fee.
The 26-year-old forward made eight appearances for Pompey after signing from Bromley last summer.
Most of his appearances came in the EFL Trophy, with his only Blues goal arriving in a last 16 tie at Southend.
Dennis’ impressive performance in that game saw him collect the competition’s Player of the Round award.
He also featured in a league loss at Oxford and both of the FA Cup ties against Queens Park Rangers.
Leyton Orient secured the National League title last season to return to the EFL following a two-year absence.
Everyone at Pompey would like to thank Louis for his contribution to the club and we wish him well for the future.
