Quoting from THA:
Gustav Schäfer was the victim of a brutal attack this past weekend. He required over 30 stitches as the result of his injuries, which was two blows at the head with a bottle.
TH Manager David Jost said that there were two offenders and the attack took place in a disco in Gustav’s home town of Magdeburg. The police are involved. The band members have not yet spoken about the incident.
Seems that Gustav is ok and recovering atm.
To send Gustav some of Your Love, here's the fanmail address. Don't be short of the stamps, if you want to be sure it will reach it's destination
