Pepper spray (also known as capsicum spray) is a lachrymatory agent (a chemical compound that irritates the eyes to cause tears, pain, and temporary blindness) used in policing, riot control, crowd control, and self-defense, including defense against dogs and bears.
In Nigeria, it has come to our knowledge that possessing that spray in public is illegal and it might get you arrested.
This was evident in a reply to a twitter user who according to her was in poice custody because she was found with a pepper spray.
The user with the handle @yoitspizzu tweeted ;

Yomi Shogunle, who is the assistant Commisioner of Police in the state replied ;
