KPRC-2 is reporting that security around the ship channel has been increased:
Harris County authorities stepped up security Monday around the ship channel as Election Day draws near.
Officials said they have not received a specific threat and that the increase in security is just a precaution.
However, they are already putting more deputies on patrol in the Houston Ship Channel’s petrochemical corridor.
Deputies said plants and refineries in east Harris County could be possible targets for terrorists.
“The fear is that al-Qaida or terrorist might try to influence the American election similar to what was done in Madrid prior to the elections there,” East Harris County Manufacturers Association spokesman Rick Hagar said.
Security will also be beefed up at local polling places, but officials said it would be unnoticeable to voters.
