Police have made a second arrest in relation to the bashing of a volunteer at Kawakawa's vintage railway.
The attack on Mike Bradshaw, 78, occurred on the morning of April 29 when he disturbed a group of youths rifling through cupboards in the railway shed.
He suffered a black eye, bruised ribs and a head wound in the attack.
Senior Sergeant Peter Robinson, of Kerikeri Police, said a 17-year-old male from Kaikohe appeared in the Kaikohe District Court this morning charged with aggravated injury and burglary.
It followed the arrest of a 15-year-old male last week who had also appeared in court.
