Guerrilla Broadcasts on the Shanghai Metro

Rumor floating around on the BBSes, copied from the Ming Pao Daily in Hong Kong (google cache):

昨日一个名叫「我爱榨菜君」的网友发表文章称，于昨日上午6时许乘坐地铁2号线，有4名男子在陆家嘴站上车，「穿着黑西装，面容严肃，非常之一本正经，在车上站成了一排」，然后4人各拿出1个录音机，开始播放「我们支持西藏独立」的录音，还「请大家上飞机时记得携带汽油炸药酒精」等。当时车上乘客不多，无人採取任何行动，4人放完录音就跑到另一车厢。

此外有网友称，有朋友停泊在上海音乐学院门前的汽车被喷涂上藏独字样和符号。

Yesterday a netizen called “I Love Mustard King” posted an article, yesterday morning riding the No.2 metro line, 4 men got on at Liujiazui Station [wearing black suits, solemn expressions, unusually serious, entered the car in a row], then the 4 each took out a tape recorder, began to play a [I support Tibetan Independence] recording, as well as [Please Everyone, When Boarding the Aircraft Remember to Bring Gasoline, Explosives, Oil], etc. At the time there weren’t many passengers, no one did anything, the 4 men ran to another car after the recording finished.

Other netizens report friends at Shanghai Music College cars were graffitied with Tibetan independence slogans and symbols.

Either there’s a really imaginative poster out there, or Shanghai is the first victim of Pro-Tibetan Independence performance artists. The article also claims that in the past couple of days Shanghai police have already confiscated more than 100 “volatile materials”. [此外，上海公安开箱检查地铁乘客行李以来，两日已检获百余件易爆物品。] Nail polish remover or C-4?
