Germany has deported an 18-year-old Afghan asylum-seeker who was recently convicted over a string of assaults that prompted a public outcry.

Authorities in the southern state of Bavaria said Wednesday the teenager was flown to Kabul together with 23 countrymen whose asylum bids had also been rejected.

The swift deportation reflects Germany's lowered tolerance for migrants who commit crimes.

The Afghan, whose name wasn't released for privacy reasons, received a six-month suspended sentence earlier this month for being part of a group responsible for a series of drunken assaults in Amberg in December in which 15 people were hurt.

Two other Afghans and an Iranian were also convicted over the assaults. It wasn't immediately clear whether those men, too, were being deported.
