Before Friday's Scottish Premiership match, a flare was lit in the Celtic end before a green smoke bomb was thrown on the pitch.
After Kris Commons scored the first goal in Celtic's 5-0 win, a missile thrown from the away support flew over Hoops goalkeeper Fraser Forster's head and play was quickly halted after Motherwell restarted when a green smoke bomb went off on his goal-line.
In total 18 smoke bombs were used along with three fireworks, according to police.
Dozens of seats had also been broken in the middle-lower section of the South Stand, just above where a Green Brigade banner had been displayed.
On Saturday the club issued a statement, it said: "Clearly we are appalled by the scenes from last night's match and the actions of a small minority which have again tarnished the great reputation of the club and our supporters on a night when our team produced such a fantastic performance.
"We are currently investigating these events and will update our supporters early next week."
Celtic are set to foot the bill for the damage caused under a reciprocal agreement between clubs but could also find themselves facing a Scottish Professional Football League investigation once the league studies its delegate report.
A Police Scotland spokeswoman added: "During the course of the match, 18 smoke bombs, three fireworks, and one flare were set off.
"Significant damage was caused to seats within the ground and we are looking into this matter along with the club to establish the circumstances.
"There were no arrests made inside the ground."
The latest incident follows after Uefa launched an investigation after Celtic fans unfurled a pro-IRA banner during the Glasgow side's Champions League clash with AC Milan last month.
