Logan police say several sexual assaults over the past two weeks appear to be related.

Lt. Randy Auman said Monday that Logan investigators are looking into one rape, two attempted rapes and several sexual assaults, while another rape is being investigated by North Park police.In at least three of the cases, the victims have given similar descriptions of their assailant, he said.

"These assaults were committed by a lone male who approaches his victims on foot, usually from behind," Auman said.

The assailant has been described as a white male in his early 20s, Auman said.

The ages of the victim victims range from 14 to 23 and all the assaults, including two in the city park, have occurred before midnight.

The Police Department has cautioned women to avoid walking alone after dark, especially in poorly lighted or isolated areas.
