SARASOTA -- A downtown Sarasota office building is on lockdown after the delivery of a suspicious envelope, according to Sarasota police.
The incident happened about 2 p.m. at Plaza Five Points, 50 Central Ave.
"The envelope had a pumpkin and the words 'TNT' and 'kaboom' written on it," police said in a news release.
Officials later determined the envelope did not contain explosives and was not hazardous, according to police.
The letter was not addressed to a specific tenant in the office building, police said, just to the building.
The return address was Plaza Five Points, according to police.
"Everyone is safe inside the building," police said. "At this time, no one is being allowed in or out.
At about 3:50 p.m., police said, "At this time, no evidence the incident at Plaza Five Points and Westfield Southgate are connected. Both are suspicious incidents under investigation."
Earlier in the day, the mall was closed after someone threw an unknown substance into a store.
Officials determined the substance was not harmful, and the mall was reopened.
