The private daily newspaper el-Watan published a story on its website Wednesday saying Hatem Aboul-Nour was imprisoned on Tuesday after the Northern Cairo Military Tribunal issued its verdict. Aboul-Nour had been detained for two months prior to his sentencing.
It is not clear whether he was caught while he was working. However, the paper described his sentence as "dangerous precedence." It said the ruling comes at a time "the Egyptian people (are) struggling against authoritarianism."
The newspaper urged the army to release Aboul-Nour.
Egypt's military tribunals are known for issuing swift and harsh verdicts.
