Qld man stabbed defending elderly man

A Queensland teenager is accused of stabbing a Good Samaritan who tried to prevent a group of youths from accosting an elderly man on a mobility scooter.

The 26-year-old man was stabbed when he confronted the three teenagers as they hassled the man on a pathway behind a service station at Heritage Park, south of Brisbane, on Tuesday afternoon.

He managed to restrain his alleged attacker and marched him into the service station where police were called.

The victim suffered non-life threatening injuries, and the 15-year-old boy will front Beenleigh Childrens Court on Wednesday, charged with acts intended to cause grievous bodily harm.
