A man has been arrested after multiple boats were tampered with at Taupō Marina.
Police were called about 9am Sunday when a boat owner discovered his vessel untied.
Further investigation revealed that several other boats had also been interfered with, a statement from police said.
Coastguard Lake Taupō volunteers alerted the police to a potential suspect. When officers tried to speak with the man, he jumped into the water and swam across the Waikato River to the Nukuhau side.
