UPDATE: All the stolen trucks were recovered by late Tuesday.
Police recovered two stolen U-Haul trucks blocks away from one another in the Kingsessing section of the city Tuesday morning. A third stolen truck was found in North Philadelphia.
Three of the recovered trucks were stolen on Sept. 11 from 12th and Washington Streets in South Philly. A fourth truck stolen that day -- a Budget Rental vehicle -- was found late Tuesday night at Chadwick and Reed Streets in South Philly.
A total of six trucks were stolen since Sept. 3, according to police -- two of which were found almost immediately.
Stolen Rental Trucks Cause Terror Concern
The first of the trucks found Tuesday was recovered at 54th and Trinity. The second, a half-block away on 54th and Chester. Both were vandalized, according to police.
The third was discovered on the 3200-block of North Park Avenue in North Philadelphia.
The Philadelphia Police Homeland Security Office, the bomb squad and their K-9 unit were brought in to search the stolen vehicles.
"We were very concerned due to the fact that four U-Haul-type vehicles were stolen in Philadelphia on Sunday, 9/11," Police tell NBC Philadelphia. "These U-Haul vehicles can be and have been used in the past to transport explosive devices."
After a thorough inspection, authorities do not believe the thefts have anything to do with 9/11.
