It's every parent's worst nightmare. A woman from Peru lost all four of her children at Berlin's main train station Monday after briefly turning her back on them to buy a ticket.

German police say the tearful mother approached officers, who were able to find two of the children wandering around the station.

A third turned up at another station in Berlin.

The fourth child, aged 3, was discovered by a conductor on a high-speed train bound for Leipzig.

Police said Tuesday that the family, who reside in Italy, were eventually reunited and were able to continue their journey to Munich the same day.
