A warning for business owners to be on high alert. That word from Greenville police after two businesses along Memorial Drive were robbed Monday in unrelated incidents. The first happened at the Kangaroo Express at 2:30 in the morning, the second at a Jiffy Lube around 10:30 in the morning. Corporal Kip Gaskins of the Greenville Police Department says a daylight robbery like that is a reminder business owners need to be proactive. Gaskins says the two suspects involved in the Kangaroo Express robbery have been arrested. Suspects in the Jiffy Lube case remain on the loose.
