It has been reported that the National Science Foundation has suspended more than $2 million in grants to the University of Connecticut.

The move came after a foundation investigation found that two of the university's professors used the grant money to buy products from their own company, Connecticut state auditors revealed Friday.

Auditors John Geragosian and Robert Ward also said that officials of the university failed to inform the auditors about the suspended grants.

They also said that as per law they were to be informed about the professor's actions but they were not. The auditors notified Gov. Dannel P. Malloy about the frozen grants in a letter Friday.

Geragosian and Ward told that two professors of the university, whose names were not released, made $253,500 of purchases in 2013 using foundation grant money to buy 15 acoustic modems from their company, Aquatic Sensor Network Technology.

It was also told that the professors signed purchase orders that included statements certifying that they had no financial or other beneficial interest in Aquatic Sensor Network Technology, the auditors said.

The professors later said they didn't read the portions of the orders that included those statements and they submitted the amended forms disclosing their conflicts of interest, they added.

The National Science Foundation in December notified that the university was suspending seven grants to the school pending its investigation. The grants originally totaled about $4.6 million, and about $2.3 million of the grants were still unspent and was frozen.

University of Connecticut released a statement saying that the school officials would have blocked the purchases if the professors had disclosed their conflicts of interest as principals of Aquatic Sensor Network Technology.

It further told that they have launched their own investigation, and three professors are under review.
