M&T Bank's search for office space to accommodate at least 1,000 technology workers has ended at One Seneca Tower downtown.

In a deal that's been in the works since earlier this year, Buffalo-based M&T (NYSE: MTB) has agreed to locate a tech hub in the vacant, 38-story tower. M&T will occupy all or portions of floors 7 through 22 and the western plaza addition facing Pearl Street, according to sources close to the deal. The bank is expected to formally announce the location Thursday.
