The Jacksonville Sheriff's Office is working a possible trend of robberies and sexual assaults on the Westside.
Police said the incidents happened in the area of South Lane Avenue and Manotak Avenue in March and May.
There were four reports of an armed robbery in March along with two reported sexual assaults in May, JSO said.
Police believe that the same suspect was involved because of a similar suspect description.
The suspect is said to engage victims via dating websites and other social networks, police said.
JSO is cautioning those who use social media to meet others to always meet in a public place and do not go alone.
Anyone with information relating to these incidents should contact JSO at 904-630-0500 or Crime Stoppers at 1-866-845-TIPS.
