A stash of money and checks was discovered behind a bathroom wall by a plumber working at the megachurch of televangelist Joel Osteen in Houston, Texas.

The revelation was reported Thursday with Morning Show radio host George Lindsey being told about the Nov. 10 find during repair work at the Lakewood Church, according to KPRC 2.

"There was a loose toilet in the wall, and we removed the tile," a caller said. "We went to go remove the toilet ... I moved some insulation away, and about 500 envelopes fell out of the wall, and I was like, 'Oh wow!'"

The caller explained to Lindsey that, upon discovering the stash of envelopes filled with cash and checks, he immediately "contacted the maintenance supervisor" and had the money turned in.

Lindsey said he was in disbelief upon hearing that the plumber had turned in the money. "We were like, 'What are you talking about?'" Lindsey said the caller explained that "in 2014 there was a big story about money being stolen from Lakewood church that they never recovered."

More than $600,000 in the form of cash, checks, and credit information was stolen out of a church safe back in 2014, according to Christianity Today.

An official from the church acknowledged that money and checks had been discovered while repair work was being done, according to the KPRC 2 report, which noted that Houston police are still investigating the seven-year-old case involving the disappearance of $600,000.

Crime Stoppers of Houston told the news outlet it is offering a $25,000 reward leading to the charge and arrest of a potential suspect. Previously, Crime Stoppers offered a $25,000 reward for any information regarding the theft.

The Washington Examiner reached out to Lakewood Church for comment.
