TEMPE, Ariz. -- A man who admitted being on "bath salts" prompted a late-night search at Tempe Town Lake on Monday.
Police said the man jumped in the lake at about 10 p.m. and swam around then got out.
He told responding officers that he had ingested bath salts earlier in the evening, according to Molly Enright, spokeswoman with the Tempe Police Department.
The man reported that there may have been another person in the lake with him. Enright said although he had an "altered level of consciousness," police took the report seriously and searched the lake for several hours.
At one point, as many as 30 police and fire personnel were out on the lake, but no one else was found. Police continued to search for the possible second person Tuesday morning.
The man was taken to a local hospital for monitoring. At this time, he has not been charged.
His name has not been released, but Enright said he is approximately 33 years old.
Police and fire crews spent more than an hour trying to get a naked man out of Tempe Town Lake last month. Police reportedly found drug paraphernalia on Chris Brown, 38, who shed all but his socks before going into the lake on June 20.
It is against city code to swim in the lake.
At the time, police said Brown was facing charges of indecent exposure, failure to identify, obstruction of a public thoroughfare, defecating in public, possession of drug paraphernalia, and use of water for swimming.
