Police say one of two vans stolen from a World Trade Center contractor has been found.

The NYPD has been concerned about the two thefts and a third in New Jersey because of unconfirmed threats that al-Qaida was planning a car bomb attack. But police reiterated Sunday that they'd found no evidence linking the thefts to a terrorist plot.

The two dark green Chevy vans had been stolen this month from Tully Construction. The company has been involved in recovery work at the site and is doing roadwork near 1 World Trade Center.

One of its vans was recovered late Saturday on a residential block in Queens. The other is still missing.

Also missing is a white van stolen from a storage facility in Jersey City, N.J.
