A tourist viciously stabbed by a crazed homeless woman inside a bathroom at Macy’s Herald Square had been changing her 10-month-old daughter at the time, sources told The Post.
The 38-year-old mom, who was visiting from California, was in the seventh-floor bathroom with her baby when she was repeatedly knifed Thursday afternoon, the sources said.
The victim suffered knife wounds to her back, shoulder and arm in the unhinged attack that unfolded during the holiday shopping rush at the packed flagship store in Midtown.
The alleged attacker, Kerri Aherne, 43, was arrested on charges of attempted murder, assault and weapon possession, cops said.
Aherne, originally from Massachusetts, is homeless, according to police.
The victim, who had been shopping with her husband and child, was taken to Bellevue Hospital in stable condition.
She was treated for multiple stab wounds to her back and a laceration on her right arm.
In California, the mom works as civilian for the state’s sheriff’s office where her husband is a sheriff, sources said.
“We are deeply saddened about the incident that took place today as the safety of our customers and colleagues is our top priority,” a Macy’s spokesperson said in a statement.
