        天津的日租界,是日本帝国主义经营的侵略中国的桥头堡。日租界当局,为了制造社会混乱,乘机扩大对中国的侵略,便收买、豢养了一小撮汉奸、地痞和武装匪徒,不穿军装,没有番号,手持武器,为非作歹,称为“便衣队” 。从1926年到1935年,日本特务机关,曾经多次驱使这伙歹徒,进行暴乱,为日本帝国主义侵略中国寻找借口。
        1926年3月,便衣队进行了第一次暴乱。当时,奉系军阀李景林等组成的直鲁联军,得到日本驻屯军的支持,攻打驻守天津的冯玉祥国民军。为了配合李景林的行动,潜伏在日租界的便衣队也蠢蠢欲动。他们冲出租界,鸣枪呼叫,占领了直隶督军办公署、警察厅及河北、河东一带地方。在便衣队出动的同时,日租界警察、日本义勇队也武装待命,为便衣队做后盾。
        1928年,日本帝国主义为了继续制造动荡不安的局面,又策划了一次便衣队暴乱。
        1931年11月8日晚10时30分,也就是“九一八”事变后,日本关东军特务机关长土肥原和天津驻屯军司令官香椎浩平,再次策划天津便衣队暴乱,妄图将华北变为第二个东北。并且乘便衣队暴乱之机,护送溥仪到东北,建立伪“满洲国”。便衣队以李际春、张璧为头子,纠集2000多名爪牙,在日军支持下,从海光寺日本兵营冲出,分成几路,向华区开枪射击。先后将驻南市公安局一区六所、驻海光寺二区六所占据; 并在东马路、南关下头分途骚扰。暴乱被东北军组成的天津保安队反击,便衣队狼狈逃回日租界。至12时许,将一区六所夺回,俘获暴乱分子10余人和多支枪械。翌日,保委队又击毙暴徒3人,拘获61人,就地枪决主要分子10人,解往北平37人,其余送第二军军部。
        1931年11月26日晚8时,便衣队发动又一次暴乱。日军以重炮向公安局、省政府、市政府轰击,并向闸口进攻。这两次暴乱,无辜民众死伤多人,万余户流离失所,工商业损失3000多万元。
