According to some local newspapers, and now an increasing number of independent news and blog sites, Egyptian police has to-date arrested 155 non-fasters, who were caught eating/smoking/drinking.

Ramadan’s fasting hours in Egypt go from Sunrise (approx. 4.15) until sunset (approx 6.15), in other words, lasts for 14 hours. Safe to say, 6 of these hours are spent sleeping, if not more.

According to those interviewed post their release, the arrests were random, and some of those arrested were fasting, but just caught buying food or drinks.

While currently, nothing in the Egyptian constitution or law gives legitimacy to this, some worry that it might become a manipulation of the present law that allows punishment to any moral offender, usually punished for things like public nudity or intense displays of public affection.

The reports are yet to be completely denied or confirmed by any official source, however, talks surrounding the incidents have been increasing in scrutiny and controversy, while some rumors have it that Al Azhar is encouraging such behavior and hopes that a law be passed to legitimize the arrests.

Such laws are known to exist in more radical countries following the Islamic Sharia, such as Pakistan, Saudi Arabia and Kuwait.
The Egyptian constitution does not follow the Islamic Shari’a, however many of its laws are derived/adapted from it.
