Defender heads off
The Latvian international had been on a short term contract with the U's but has now departed.
He made nine appearances for the U's, scoring his only U's goal in his final match last weekend.
It was hoped that he would remain here in north Essex but he signed an eighteen month contract with the Greek outfit late on Thursday.
Boss Tony Humes said of the departure: "We're sorry to lose Kaspars."
"He has done exactly what we needed from him and it's disappointing that he has decided to go elsewhere."
"I'd like to thank him for his time here and wish him well for the future."
