DALLAS - Police are on high alert as the Holy Land Foundation trial continues in downtown Dallas.

The trial is centered around terrorism and The Holy Land Foundation, who is accused of funneling money to terrorist organizations. The department has a command post near the federal courthouse to watch for suspicious people.

"We evaluate continually everyday, and will be during the trial," said Deputy Chief Vince Golbeck, Dallas Police Department.

Several recent incidents prompted the Dallas Police Department and federal authorities to beef up security in some areas. Last week, police received information about a suspicious man who appeared to be Middle Eastern and was said to have been spotted checking out a TXU plant near downtown two days in a row.

"We are staying alert on those particular properties," Golbeck said.

Also, police said the lead U.S. attorney in the case, Jim Jacks, had his car vandalized at his home in North Dallas. However, there were also other cars in the neighborhood vandalized as well. But as a precaution, the U.S. Marshall's Office has stepped up security at Jacks' home.

Police said many of the tips are not terror related, but are checking everything, leaving nothing to chance.

"The majority of these things we are going to be very conservative, very thorough to track down any kind of intel that comes to us like that," Golbeck said.
