Fall River police are trying to "clean up" an area authorities said is overrun with criminal activity. 

"Operation Clear Path" was launched yesterday morning on the Quequechan River Rail Trail between Rodman Street and Brayton Avenue. 

Police said in the last three years there have been hundreds of calls to that area for sexual assaults, overdoses, robberies, fires and armed assaults. 

During yesterday's sweep, police reported 33 people were arrested.
