Narrative:

This incident happened as my student was doing touch-and-goes in l-hand pattern in a control twred airport, bdr, ct. We were doing touch-and-goes on runway 11 and an aircraft had reported east of the field. The tower had asked us to extend our upwind so he could allow that traffic to enter the pattern. So we extended. While upwind, he cleared a C172 for takeoff (he was departing the airport) to follow us. I told my student to extend for 1 mi which we did and then we started our crosswind. As we turned for downwind, my student pointed out a cessna about 25 ft off our left wing. It turned out the cessna that was supposed to follow us turned crosswind before us. We maneuvered to avoid him. The tower had called the cessna and told him that he was supposed to follow us and that he cut in front of us. The cessna responded that he wasn't staying in the pattern. The tower scolded him, saying he was still supposed to follow us. He was #2. I don't think the cessna still realized what the tower meant.

Title: AN INSTRUCTIONAL FLT HAD A CESSNA NEAR MISS WITHIN THE TFC PATTERN AT BDR.

Narrative: THIS INCIDENT HAPPENED AS MY STUDENT WAS DOING TOUCH-AND-GOES IN L-HAND PATTERN IN A CTL TWRED ARPT, BDR, CT. WE WERE DOING TOUCH-AND-GOES ON RWY 11 AND AN ACFT HAD RPTED E OF THE FIELD. THE TWR HAD ASKED US TO EXTEND OUR UPWIND SO HE COULD ALLOW THAT TFC TO ENTER THE PATTERN. SO WE EXTENDED. WHILE UPWIND, HE CLRED A C172 FOR TKOF (HE WAS DEPARTING THE ARPT) TO FOLLOW US. I TOLD MY STUDENT TO EXTEND FOR 1 MI WHICH WE DID AND THEN WE STARTED OUR XWIND. AS WE TURNED FOR DOWNWIND, MY STUDENT POINTED OUT A CESSNA ABOUT 25 FT OFF OUR L WING. IT TURNED OUT THE CESSNA THAT WAS SUPPOSED TO FOLLOW US TURNED XWIND BEFORE US. WE MANEUVERED TO AVOID HIM. THE TWR HAD CALLED THE CESSNA AND TOLD HIM THAT HE WAS SUPPOSED TO FOLLOW US AND THAT HE CUT IN FRONT OF US. THE CESSNA RESPONDED THAT HE WASN'T STAYING IN THE PATTERN. THE TWR SCOLDED HIM, SAYING HE WAS STILL SUPPOSED TO FOLLOW US. HE WAS #2. I DON'T THINK THE CESSNA STILL REALIZED WHAT THE TWR MEANT.
