Police discovered two cars that were used by some of the Albanian convicts who escaped from Trikala prison earlier this year near a village in Evrytania, central Greece, on Thursday.
One was a patrol car that had been taken after a group of convicts shot dead a 37-year-old police officer at a road block in Distomo on June 16.
The other vehicle had been stolen from a village in central Greece.
Both cars were found in ditches near the village of Perithiotissa and had been covered with foliage.
Police shot dead two men near the town of Koniska on Tuesday as they tried to apprehend some of the fugitives.
The escaped inmate killed was named as 27-year-old Edison Lika, while the other man shot by police was identified as the fugitive’s uncle.
Six of the 11 Albanian prisoners that escaped from jail in March are still at large.
