Akron police Wednesday nabbed a suspect who may be involved in a recent string of robberies involving sales of phones and electronics through social media.

The break apparently came after another robbery, at least the ninth of its kind since Dec. 30.

This time, a man trying to buy a mobile phone agreed to meet an online seller inside a business in the 1200 block of South Arlington Street about 8 p.m.

Once inside the business — which police did not publicly identify — the buyer looked at the phone that was purportedly for sale and put cash on a counter to buy it. Police said a man who was pretending to sell the phone then grabbed the cash and the phone and bolted from the store.

The victim called police and officers, with the help of a K-9, tracked the suspect to an apartment in the 800 block of Palmetto Avenue, police said.

The suspect first gave police a false name, but ultimately identified himself as Dwayne A. Nixon, 18, of Triplett Boulevard, police said.

Nixon was charged with misrepresenting his identity and theft.

Detectives are now investigating whether Nixon was also involved in a string of similar crimes.

Police on Thursday again warned people buying and selling things through social media to be cautious.

Among other things, police recommend looking into the seller's online profile before agreeing to meet. And then, police said, only agree to meet in a well-lit, busy public place.
