A Staten Island man who cops say was found hiding cocaine and steroids in the drop ceiling of his business is trying to blame his legal woes on disgraced ex-Congressman Michael Grimm — who once dated the man’s ex.

Michael Tommasi, 56, was arrested in December, after he was allegedly caught breaking into the Sunset Park office of his company, Interior Metals, by using a hammer to smash the knob off the front door, according to police and a criminal complaint.

Once inside, Tommasi hammered his way into an office, where a small amount of cocaine and 30 bottles of anabolic steroids were found hidden above the ceiling tiles, which had been disturbed, authorities said.

Initially arrested for felony drug possession and burglary, the charges were later reduced to misdemeanors.

Tommasi says he was wrongly arrested, and it’s because Grimm, who Tommasi claims is dating his ex-wife Antonella, used his influence with the NYPD, according to a new Manhattan Supreme Court lawsuit.

The Tommasis, who are in the midst of a bitter marital split, had for years jointly operated Interior Metals and split the profits.

But as they parted ways, Tommasi claims Antonella worked behind the scenes to oust him.

On Dec. 5, Antonella removed him as company president and chairman of the board without him knowing, Michael Tommasi claims.

When Tommasi showed up for work on Dec. 6, Antonella, who holds 51 percent of the company’s shares so it qualifies as a woman-owned business, called the cops.

“Antonella utilized the political connections of her ‘boyfriend,’ Michael Grimm, in order to persuade the police to arrest Michael at his place of business” and to get an order of protection barring him from the premises, the hubby alleged in the lawsuit against his estranged spouse.

Grimm and Antonella split a year ago, well before the December arrest, a source said.

Antonella Tommasi has also siphoned off $600,000 for herself in a bid to lower the value of the $10 million company and force Michael, who owns 49 percent of the shares, to sell out to her on the cheap, he said in court papers.

While “falsely and maliciously” accusing Michael of stealing from Interior Metals, Antonella has used company cash to pay for hotels, personal meals and parking, her ex charges.

Interior Metals makes products like air conditioning sleeves and radiator covers.

Former FBI agent Grimm served eight months in prison for tax fraud for under-reporting wages at a restaurant he owned, and filing false tax documents. He’s also known for threatening to throw a NY1 reporter over a Capitol building balcony.

Antonella Tommasi could not be reached.
