LAKEWOOD, Ohio -- A U.S. Coast Guard boat and helicopter scoured the edge of Lake Erie Wednesday morning in search of a man who jumped off a break wall at the edge of Lakewood Park.

There were no signs of the man after more than 10 hours of searching.

An auxiliary police officer saw the man on the break wall about 9:30 p.m. Tuesday and told him to come down, Coast Guard Petty Officer Christopher Yaw said.

The man jumped into the lake, swam about 50 feet and was overcome by a wave and didn't resurface, Yaw said.

The auxiliary officer called the Lakewood Fire Department, who reported the matter to the Coast Guard.

Coast Guard officials sent several boats and a helicopter to search the lake.

Sections of Lakewood Park along the shore are closed for construction, but a walkway along the edge of the lake remains open.

The search marks the second time this summer that rescue crews looked for a man who jumped into Lake Erie from Lakewood Park.

A still unidentified man was spotted in the construction zone June 24, and after he was confronted by two construction workers, he took his clothes off, climbed a fence bordering Lake Erie, police said.

His body washed up in Clifton Lagoons days later.
