A man wanted by police in relation to a serious assault is missing in the Waikato River.
Police are searching for the 36-year-old, who fled officers in Hamilton last night.
A police dog tracked him to the edge of the Waikato River, near the Cobham Bridge.
The river and its banks were searched using the police boat and Eagle helicopter and about an hour later, the man was spotted in the water but disappeared before police could reach him.
