His 35-year-old wife, who remains unnamed, was taken to Bellevue Hospital in critical condition and is now stable, police said. The New York Daily News reported she’s pregnant and doctors at Bellevue were able to reattach her arm.

A wanted sign along with a photo of Lu was shared by the New York Police Department’s 72nd Precinct on Twitter Thursday.

“WANTED: Male, Asian, approximately 5’6, 130 lbs for felonious assault that occurred on 55th street between 4-5 ave on June 21st. Help us find this individual, share information. #800577TIPS,” the tweet read.

The couple’s neighbors told the NYDN that the two have a 7-year-old son and lived in the Sunset Park neighborhood of Brooklyn for about two years.

One neighbor told the outlet the family kept to themselves.
