A photo of a now retired Jersey City, NJ police officer helping a teenager tie his tie has gone viral.

Lashambi B. Moore shared a photo of Officer Charlie Casserly on Martin Luther King Drive with a local teen, wearing khakis a button-down shirt and sweater vest. The teen did not know how to tie his tie and asked Casserly for help.

“Charlie pulled the patrol car over, got out and spent nearly a half an hour teaching the young man how to tie a tie,” Moore wrote on Facebook.

The photo was taken on July 9, just before 10 a.m.

Moore told The Jersey Journal she took the picture because it was something good that she thought others would want to see.

“I only posted it to make others feel good because it made me feel good,” Moore said.

Moore said Casserly first demonstrated how to tie the tie on himself. The young man tried for himself, and Casserly then fixed it to look proper.

Since the post has gone viral, Facebook users have been chiming in to thank Casserly for being a dedicated officer on the force and congratulated him on his retirement.

“Outstanding. More of this please,” Fletcher Gensamer wrote on the post. “Thank you Officer Charlie for your service.”

Carmine Disbrow, president of the Jersey City Police Officers’ Benevolent Association, said Casserly’s actions are representative of the department.

“This picture represents 40 years of Charlie Casserly not just of being a law enforcement officer, but also of being a role model, a leader, and a mentor,” Disbrow said. “It also is an accurate depiction of why Officer Casserly, and so many other men and women, choose to wear the badge, and their efforts to make the communities they serve better and stronger.”
