Narrative:

We were cleared for takeoff on runway 22. As we began our roll we heard tower call for a small aircraft (I can't remember the call sign -- I believe it was a high wing single engine cessna) to 'stop.' we looked and the runway was clear and we saw no movement from either side of the runway. Takeoff was continued. At around 100-110 KTS, we saw movement to the right at the same time the tower called for the aircraft to 'turn left immediately.' he called that twice and told the aircraft that there was a jet departing on runway 22 and he was not cleared for takeoff, but only told to go into position and hold. We continued the takeoff because the aircraft did start the left turn and continued his climb. At this time I could see that the other aircraft would not hit us, but to ensure that would be the case, I delayed the rotation of our aircraft until we were past his line of flight. After landing at our destination, I called hobby tower. They informed me that no action was being taken. We had correctly been cleared for takeoff on runway 22 and the other aircraft had not been given takeoff clearance on runway 12L, but did so anyway.

Title: AN ACR MLG FLC RPTS THAT DURING THEIR TKOF THEY HAD A CLOSE ENCOUNTER WITH AN SMA WHO PERFORMED AN UNAUTH TKOF.

Narrative: WE WERE CLRED FOR TKOF ON RWY 22. AS WE BEGAN OUR ROLL WE HEARD TWR CALL FOR A SMALL ACFT (I CAN'T REMEMBER THE CALL SIGN -- I BELIEVE IT WAS A HIGH WING SINGLE ENG CESSNA) TO 'STOP.' WE LOOKED AND THE RWY WAS CLR AND WE SAW NO MOVEMENT FROM EITHER SIDE OF THE RWY. TKOF WAS CONTINUED. AT AROUND 100-110 KTS, WE SAW MOVEMENT TO THE R AT THE SAME TIME THE TWR CALLED FOR THE ACFT TO 'TURN L IMMEDIATELY.' HE CALLED THAT TWICE AND TOLD THE ACFT THAT THERE WAS A JET DEPARTING ON RWY 22 AND HE WAS NOT CLRED FOR TKOF, BUT ONLY TOLD TO GO INTO POS AND HOLD. WE CONTINUED THE TKOF BECAUSE THE ACFT DID START THE L TURN AND CONTINUED HIS CLB. AT THIS TIME I COULD SEE THAT THE OTHER ACFT WOULD NOT HIT US, BUT TO ENSURE THAT WOULD BE THE CASE, I DELAYED THE ROTATION OF OUR ACFT UNTIL WE WERE PAST HIS LINE OF FLT. AFTER LNDG AT OUR DEST, I CALLED HOBBY TWR. THEY INFORMED ME THAT NO ACTION WAS BEING TAKEN. WE HAD CORRECTLY BEEN CLRED FOR TKOF ON RWY 22 AND THE OTHER ACFT HAD NOT BEEN GIVEN TKOF CLRNC ON RWY 12L, BUT DID SO ANYWAY.
