I DONT KNOW IT THIS IS CONFIRM OR NOT..SO DONT TAKE IT SERIOSLY :D

On January 18th, the group was at the airport to visit the Philippines but they were delayed due to visa issues with EXO-M. This caused a greater sasaeng turnout than usual. 

Kai was standing near the stairs when a sasaeng fan grabbed him, causing him to fall down and injure his chin and knee. Other sasaengs reported seeing sasaengs near him touch him in inappropriate places. He was unable to get up on his own, leading Baekhyun to try and lift him up.
A sasaeng was overheard saying, "I need to take his picture, move your head", among other swears to Baekhyun.

Tao apparently wrote on his Weibo in broken Korean asking fans to please stop because he doesn't want his members getting hurt anymore.

Before, Jongin had suffered an incident where he was holding a stuffed animal a fan had given him. He couldn't pass through security so they searched him and found a hidden camera in the teddy bear's eye that had been on and filming the entire time.

I found another blog post that had a compilation of sasaeng acts against EXO. I don't know if any of these are confirmed or not.

1. A sasaeng fan bought the same van as EXO and used it to wait outside EXO's schedules. Luhan actually tried to get on it once but his manager freaked out and pulled him out.

2. Kyungsoo once had a bruise on his eye because a 'daepo sasaeng' (daepo = DSLR camera) hit him in the eye.

3. Tao was at a foreign hotel for a schedule and sasaengs had installed a recording device in the bathroom that recorded noise of him showering and humming a song.

4. Kai's teddy bear incident. [Netizen comment: [+26, -0] EXO Kai also received a stuffed animal as a gift from a fan while at the airport. The doll couldn't get past security so they searched it and found a hidden camera in its eye.]

5. Lay went back to his waiting room to find all their bags opened and their contents strewn around

6. A sasaeng fan stuffed something into a member's bag and ran away and it ended up being her underwear.

7. Sehun and Luhan were sexually harrassed by them.

8. Sasaeng fans were on their knees crawling around outside EXO's dorm so when people asked what they were doing, they said they were trying to find EXO's stray hairs.

[According to the netizenbuzz, several fans have pointed out that the teddy bear rumor was confirmed to be false]
