Tessa Majors was stabbed in Manhattan's Morningside Park on Wednesday

A student at Columbia University has said that he was mugged at knifepoint just months ago at the same location where 18-year-old Barnard College freshman Tessa Majors was stabbed to death.

Columbia mathematics major Yao Yu, a 20-year-old international student from China, was robbed by a pack of knife-wielding teens on August 27 on the same stairs in Morningside Park in upper Manhattan, the New York Post reported.

Yu said three suspects approached him in broad daylight as he was walking home from class.

'They asked me where I was from and if I had any money. At first, I didn't think they were threatening me, so I told them I didn't have any money. Then, they showed me an open knife, so I gave them my wallet and they took my money,' Yu told the Post.

'I was surprised this happened to me. Before I came, I heard that New York is pretty safe, but I encountered these things and it's really unfortunate,' Yu said.

Yu said that he reported the mugging to the NYPD, but was told that even though 'several people' had been robbed 'by the same teenagers' the cops couldn't do anything because 'they aren't adults.'

Tessa was also attacked by a trio of teenagers, but it is unclear whether they are the same suspects in any prior robberies.

At least two suspects in Tessa's killing, males ages 13 and 14, are currently in police custody, and law enforcement sources say that the 13-year-old confessed to attacking the Barnard student with two accomplices.

It's unclear whether a third suspect is already in custody as well, or still being sought.

NYPD crime data shows that Morningside Park, situated on a steep slope that separates Harlem from the sister campuses of Columbia and Barnard, has become a hotbed of violent crime in recent months.

At least 20 robberies have been reported in and around the park this year, the data shows.

In the 26th Precinct, which includes Morningside Park, has seen a 27 percent increase in robberies so far in 2019, compared to the same period last year.

Burglary, petty larceny and misdemeanor assault are also up by double digits in the precinct.

Citywide, the stats are less dramatic, but murder is up 9 percent over last year, and robbery and felony assault both up around 2 percent.
