Undercover police started patrolling some of Athens’s larger squares as of last night in a bid to crackdown on teenage gangs and street violence, Public Order Ministry sources said yesterday. Law enforcement officers will monitor squares, such as in the suburb in Glyfada, which have grown into favored gathering places for gangs, especially as schools are now finishing for the summer holidays. Police will also intensify patrols on the beach zone from Neo Faliron through to Markopoulo in eastern Attica, as residents flock to the area due to the warmer weather. Following a series of meetings among senior police officials in the last few days, it was also decided that alcohol tests, stricter traffic supervision and a clampdown on clubs taking up parking areas illegally will be implemented in the parts of the city that host tens of night spots. Additionally, undercover police will put on their beach gear to keep a closer eye on swimmers and help prevent petty crimes such as the theft of purses and mobile phones.
