The police are investigating two incidents last month where a large quantity of eggs were thrown at properties and cars in three streets in the area known as Santa Margerita, Mosta.
Nationalist MP Edwin Vassallo in a parliamentary question said that 'hundreds' of eggs had been thrown on two successive Sundays at Triq Dawret il-Wied, Triq il-Bwieqi and Triq il-Fuħħar.
The minister, Carm Mifsud Bonnici, said the police had stepped up their surveillance of the area.
Contacted by timesofmalta.com, Mr Vassallo said he could not understand what was behind the incidents, but a considerable number of eggs had been thrown. The incidents have not been repeated.
