That’s no way to treat your elders.

A 76-year-old Manhattan man faces up to 15 years in prison on charges he looted $330,000 from the bank accounts of his old pal — a 98-year-old lawyer who still practiced law from a wheelchair.

Accused crook Harry Abrams ran an unsuccessful money-management business in Midtown, prosecutors said. He let his buddy of two decades, Emanuel Baetich, use an office down the hall for free.

Sharp as a tack on the brink of age 100, Baetich had kept a few private clients, prosecutors said. The no-rent arrangement lasted for years.

In July 2009, Baetich broke his hip and landed in the hospital. Before the month was out, Abrams had stolen and redeemed $330,000 in certificates of deposit from Baetich’s unlocked office, prosecutors said.
