Just three hours earlier, a 32-year-old woman was attacked at the same intersection, police said.

He’s also suspected of groping a 39-year-old woman around 9 a.m. on Aug. 9 at the intersection of 8 ^th Street and Eighth Avenue.

The earliest attack linked to the pattern was on June 25, when a 41-year-old woman was groped around 10:30 p.m. at 1 ^st Street and Eighth Avenue.

None of the victims were physically injured, police said.
